Chemical ID: CAS Formula HS Code Database of L-Citrulline

Property	Manufacturer’s Commentary
Product Name & IUPAC Name	Common name in production is L-Citrulline. The established IUPAC name used for technical registration, import, or export documentation is (2S)-2-amino-5-(carbamoylamino)pentanoic acid. This naming convention underpins regulatory traceability across multiple jurisdictions, crucial for batch-level tracking at scale.
Chemical Formula	C6H13N3O3 reflects the structural basis for analytical verification during quality control and raw material conformity assessments. Routine identity confirmation hinges on chemical formula validation via established spectroscopy or chromatography methods, typically applied lot by lot to guarantee no cross-contamination from upstream process intermediates.
Synonyms & Trade Names	L-Citrulline also appears in procurement and customer documentation as (S)-α-amino-δ-ureidovaleric acid, or simply Citrulline in many downstream formulations. Formulators often request confirmation that all nomenclature corresponds exactly to international pharmacopeia or food-grade registration where those apply – any deviation requires formal deviation approval at the production site level.
HS Code & Customs Classification	L-Citrulline generally classifies under HS Code 2922.49 (amino acids and their esters, not elsewhere specified, and their salts). Customs classification may shift per region if the product grade or end use (nutritional, pharmaceutical, or industrial) triggers country-specific tariff subcodes. Accurate code matching stems from production-grade declaration and intended customer application, with supporting documentation aligned to batch lot, shipping paperwork, and export declarations, finalized by Quality and Regulatory Affairs prior to dispatch.

Manufacturer Notes on Chemical Identification

Downstream customers often pursue verification against official registration documents before formulator approval. Consistent product identification depends on the traceability of raw materials and uninterrupted lineage of name, formula, and HS assignment. This is especially critical where end-user claims require documentation stretching back to the synthesis step, as is typical for food and pharma-grade L-Citrulline.

Any change in supplier, synthetic route, or process control parameter will prompt a temporary halt in batch release to verify continued chemical uniformity at the formula and registration level. This contributes to compliance with global customs, avoiding delays or reclassification that could complicate logistical flows.

L-Citrulline: Technical Properties, Manufacturing Process & Safety Guidelines

Physical & Chemical Properties

Physical State & Appearance

L-Citrulline produced for nutritional and pharmaceutical markets typically presents as a colorless to white crystalline powder. In process settings, moisture content and agglomeration level depend greatly on both environmental control and the step at which material is sampled. Odor remains negligible at all grades. Melting point measurements fall within a narrow window for pure crystalline grades, though technical grades may show slight deviation due to residual water or trace organics.

Solubility & Solution Preparation

The material dissolves readily in water across the pH range common in solution preparation for dietary and clinical applications. Rate of dissolution can vary based on particle size distribution and degree of crystallinity, which are both functions of the crystallization and drying stage. For consistent solution strength and clarity, dissolution should be carried out under agitation to minimize undissolved particulates in end-use formulations.

Chemical Stability & Reactivity

Citrulline’s backbone resists hydrolysis and racemization under most processing and storage conditions. Mild acidic or basic solutions do not affect chemical integrity over normal use periods. Grades intended for parenteral applications often include counter-tests for peroxide, aldehyde, and heavy metal reactivity, since the product is exposed to varied excipients and process waters during downstream mixing and filling.

Technical Specifications & Quality Parameters

Specification Table by Grade

Technical, food, and pharmaceutical grades differ mainly in purity thresholds, limits for bioburden, heavy metals, and specific optical rotation. Impurity limits and specification ranges remain tailored to end-use and regulatory requirements. The release criteria for a pharmaceutical grade batch will include enantiomeric excess and detailed impurity profiling, while food grade typically controls only total impurities and physical purity.

Impurity Profile & Limits

Impurity profile varies with raw material quality and synthesis route. Commonly monitored impurities include dipeptides, other amino acids, and process-derived byproducts. Tight specification limits for potential allergenic or pharmacologically active contaminants are standard for injectable grades, accepted at broader ranges for food and feed intermediates. Gas chromatography, HPLC, and UV-spectroscopy dominate batch release testing, with results held against grade-specific allowable limits.

Test Methods & Standards

Analytical approach always reflects final use class: compendial methods (e.g., USP, JP, Ph. Eur.) apply for pharma grade, using HPLC or specific optical rotation, while food/FCC and internal methods support food grade validation. Where no monographs exist, the final test panel reflects customer specification and relevant national food safety requirements.

Preparation Methods & Manufacturing Process

Raw Materials & Sourcing

Procurement prioritizes amino acids of certified non-animal origin for dietary and pharmaceutical markets to address regulatory and allergenic concerns. Fermentation-based or enzymatic routes leverage renewable substrates and reduce risk of adventitious contaminants.

Synthesis Route & Reaction Mechanism

Enzymatic conversion from ornithine or arginine has become common in large-scale production due to high substrate specificity and minimal byproduct formation. The older chemical routes, often involving protection-deprotection steps, remain in use only for specialty applications or for development of tailored analogs where route flexibility supersedes cost.

Process Control & Purification

At all scales, the process requires tight control over pH, temperature, and dissolved oxygen to maximize conversion and restrict side reactions. Key control points include substrate feed rates, reaction end-point detection, and in-process monitoring of byproducts. Purification relies on activated carbon, ion exchange, and multi-stage crystallization, with final drying under reduced pressure or inert gas to prevent product caking or rehydration.

Quality Control & Batch Release

Release decisions always involve batch traceability, full spectrum impurity checks, and microbial load assessment. Release specifications and internal batch records must match those of the target grade and destination market.

Chemical Reactions & Modification Potential

Typical Reactions & Reaction Conditions

L-Citrulline offers low reactivity under neutral conditions. Derivatization, typically for analytical or peptide synthesis purposes, uses protected amino functionality under controlled pH and moderate temperature. Catalysis uses standard acid or base without need for exotic reagents.

Derivatives & Downstream Products

Citrulline integration into di- or oligopeptides by enzymatic or chemical coupling serves nutraceutical and biomedical R&D. Reaction conditions reflect those of protected peptide synthesis, with temperature and solvent choices limited by stability and end-use purity needs.

Storage & Shelf Life

Storage Conditions

Bulk stocks remain stable in low humidity, at room to refrigerated temperature. Light protection proves necessary for pharmaceutical grade held in transparent containers to prevent potential degradation of trace impurities. Gas protection, typically nitrogen blanketing, prevents oxidative changes in high purity lots slated for long-term storage or transport.

Container Compatibility

Product demonstrates compatibility with polyethylene and polypropylene containers under standard warehouse temperatures. For high grade or long shelf requirements, double-layer barrier film or aluminum-lined packaging further minimizes moisture transmission and accidental contamination.

Shelf Life & Degradation Signs

Degradation in controlled storage appears mainly as increased color in crystalline powder or as clumping due to moisture ingress. Both can be detected visually and with basic analytical checks, and prompt reprocessing or quarantine depending on application risk.

Safety & Toxicity Profile

GHS Classification

Current data place citrulline outside of acute toxicity hazard classes under GHS criteria for dietary and technical grades. Hazard identification may still apply based on the impurity profile, especially when batch contains potential allergens or process residues not fully removed in purification.

Hazard & Precautionary Statements

Manufacturing environments require standard dust control and respiratory protection due to risk of airborne particles. Gloves and eye protection remain routine for powder handling. Spills present slip hazard more than any acute chemical risk and respond well to standard dry clean-up methods.

Toxicity Data, Exposure Limits & Handling

Toxicity studies confirm low toxicity for oral and dermal routes, with no evidence of sensitization for the pure compound at typical concentrations. Inhalation of dust in confined spaces should be minimized through effective engineering controls. Workplace exposure limits follow general guidelines for inert organic powders. Technical directors emphasize traceability and batch history to promptly address any adverse event, especially in high purity or direct human contact uses.

L-Citrulline: Supply Capacity, Commercial Terms & 2026 Price Trend Forecast

Supply Capacity & Commercial Terms

Production Capacity & Availability

L-Citrulline output hinges on the choice of raw materials and process route. When produced by enzymatic conversion or fermentation, annual capacity shifts alongside substrate sourcing, fermenter utilization, and downtime for cleaning or validation cycles. Mature plants have maintained output for food/pharma grade in the hundreds to low thousands of metric tons per year, but surge demand or regional supply chain disruptions (oleochemical or glucose feedstocks) can limit batch scheduling flexibility. Facility expansion can be phased, yet throughput always reflects compliance with contamination control and downstream purification load.

Grade stratification—pharma vs food vs industrial—dictates which portion of total output is available for each end-market. Compliance testing, release batch size, and final release are aligned to contract specifications, and ranked allocation takes priority for long-term partnership clients or strategic sectors.

Lead Time & Minimum Order Quantity (MOQ)

Standard lead times reflect both in-plant batch cycles and external bottlenecks—lab clearance, regulatory documentation, and packaging slot reservation. Custom packaging or high-purity grades require additional production planning lead time. MOQs vary by grade and packaging format; some applications require minimal release batch size (pallet, drum, or small pack), while pharma GMP may fix higher MOQ due to overall traceability demands. Supplier reserves surge capacity for urgent requests, but routine spot supply is constrained by annual takeaway forecasts and raw material outlook.

Packaging Options

Typically, food and supplement-grade L-Citrulline ships in fiber drums with poly liners, carton boxes, or composite bags, with packaging systems selected based on hygroscopicity and cross-contamination prevention. For pharma applications, materials with higher barrier properties and tamper-evident seals are prioritized. Final packaging solution may depend on end-market import requirements, transport method, and downstream blending or repacking needs.

Shipping & Payment Terms

Sea-freight dominates international shipments, with air-freight reserved for pilot/batch-scale or urgent needs. Shipping standards follow good distribution practice (GDP) guidelines for pharma, and food-grade shipments often require temperature or humidity logs. Payment terms reflect client status, typically T/T, L/C, or agreed credit lines for ongoing partnerships. Export documentation, country-of-origin certificates, and regulatory dossiers are handled by in-house quality and logistics teams to minimize delays at destination ports.

Pricing Structure & Influencing Factors

Raw Material Cost Composition & Fluctuation Drivers

Cost breakdown begins upstream with the choice of fermentation substrates—glucose, corn, or sugar—and enzyme or bacterial strain procurement. Regional crop failures, weather events, or commodity price hikes feed directly into substrate price swings. Utilities (steam, water, power) and processing aids—downstream filtration media, chromatography resins—contribute to batch cost. When ammonia prices rise or co-products such as urea fluctuate, conversion cost benchmarks recalibrate. Major cost upswings have tracked with disruptions in the global corn or sugar trade flows.

Process route selection (chemical synthesis vs biotransformation) shapes cost sensitivity to raw material volatility; fermentation-heavy supply chains track agricultural commodities more closely than those anchored to bulk petrochemicals. Major purification costs are driven by impurity load and grade requirements—pharma and food grades require narrower release specs, driving higher unit costs from multi-stage purification.

Grade, Purity, and Packaging Certification Price Differentials

The single largest price step derives from grade: pharma and USP/EP grades require validated cleanroom operations, full traceability, and multi-lot release documentation. Food and dietary supplement grades, though rigorous, operate to looser impurity and trace heavy metal or microbe thresholds. Application sensitivity (IV solution, oral supplement, bulk feed) governs not just purity, but packaging—GMP-certified liners, inert atmosphere filling, and serialized sealing with data logging.

Certification (Kosher/Halal/GMP) and traceable audit documentation inject cost on both a product and plant basis. Packaging units featuring anti-counterfeit measures or validated for direct contact pull higher premiums. In multi-national supply, packaging conformity to regulatory standards in destination countries incurs added cost layers.

How to Select the Right Grade

Step 1: Define Application

Production always starts by clarifying end use. For example, meeting food additive regulations means selecting raw materials and processing methods that match food safety protocols. Applications in pharma require additional documentation and often a dedicated manufacturing route to avoid cross-contamination.

Step 2: Identify Regulatory Requirements

Regulatory review remains a major checkpoint. Manufacturing experience shows regulations differ by geography and final product: nutraceuticals follow food laws; pharmaceuticals require full GMP compliance and reference to pharmacopoeial standards. Reviewing customer target market triggers selection of compliant raw materials and initiates control documentation.

Step 3: Evaluate Purity Needs

Each grade includes target specifications for purity and impurity profiles. Supplement and food products prioritize elements such as heavy metal thresholds, microbial load, and absence of allergens. Pharmaceutical production focuses on maximum permissible impurities, particularly those specified in pharmacopeias. High-purity material relies on multi-step purification, impacting yield and supply cost.

Step 4: Consider Volume & Budget

Batch size and cost are relevant. Higher-purity grades require more processing, resulting in increased costs and potential lead time extensions. For high-throughput production of food blends, bulk packaging and standard food grade is usually sufficient, but quality control still checks for lot-to-lot consistency. Custom grading may suit specialty formulations but implications for price and availability should be weighed.

Step 5: Request Sample for Validation

Before any supply agreement, validation batches allow customers to confirm process compatibility, dissolution, taste, and analytic compliance. Internal testing documents the batch’s conformity with declared specifications. Customer-specific analytical data can reveal subtle formulation impacts, sometimes prompting adjustment to grade or processing route.
