L Cysteine Hydrochloride Monohydrate Overview
L Cysteine Hydrochloride Monohydrate (synonyms: cysteine hydrochloride monohydrate, l cysteine hcl monohydrate, cysteine hcl monohydrate; CAS 7048-04-6) is the hydrochloride salt of the essential sulfur-containing amino acid L-cysteine, crystallized with one molecule of water. With a typical molecular formula of C3H7NO2S·HCl·H2O, it appears as a white to off-white crystalline powder, freely soluble in water and valued as a mild, thiol-based reducing agent. In the chemical industry—particularly fine chemicals and pharmaceutical raw materials and intermediates—this chiral building block is indispensable for peptide synthesis workflows, disulfide bond management, and as a precursor to several API intermediates.
- Relevance: Ensures redox control during peptide coupling, supports cell-culture media formulations, and contributes to parenteral nutrition compositions subject to regulatory compliance.
- Technical background: As an optically pure L-enantiomer, it delivers consistent specific rotation and high assay purity suitable for pharmacopeial compliance (e.g., USP/EP/JP where applicable). Typical expectations include tight control of impurities, heavy metals, and microbial load.
- Reliable manufacturer: Hebei Fuyang Biotechnology Co., LTD provides robust batch traceability, Certificates of Analysis, and stable global supply—key for GMP-governed environments requiring dependable inputs.
Benefits & Use Cases of L Cysteine Hydrochloride Monohydrate in Pharmaceutical raw materials and intermediates
In pharmaceutical synthesis, L Cysteine Hydrochloride Monohydrate serves multiple roles. It functions as a reducing agent to cleave or prevent disulfide bridges in peptide and protein processing, as a chiral starting material for protected cysteine derivatives used in API manufacturing, and as a precursor for well-known mucolytic and antioxidant intermediates (e.g., N-acetyl-L-cysteine). It is also incorporated into cell-culture media and bioprocess buffers to support correct protein folding and redox balance. For parenteral nutrition and amino-acid injection concentrates, high-purity grades help meet stringent quality and safety expectations.
- Applications: Peptide APIs and intermediates, S-protecting group strategies, biologics processing, media preparation, and redox-sensitive synthesis steps.
- Competitive advantages: Consistent assay and optical purity, excellent aqueous solubility, and reliable performance as a thiol-based reductant reduce variability and rework. CAS 7048-04-6 identification aids regulatory documentation.
- Supplier expertise: Hebei Fuyang Biotechnology Co., LTD aligns production with rigorous quality systems and offers flexible packaging and documentation support, enabling seamless integration into regulated supply chains.
Cost, Maintenance & User Experience
Total cost of ownership for L Cysteine Hydrochloride Monohydrate is shaped by material consistency, documentation readiness, logistics reliability, and shelf-life management. High and stable assay reduces over-dosing, minimizes deviation investigations, and supports better batch yields—directly improving ROI. Predictable lead times and competitive pricing from Hebei Fuyang Biotechnology Co., LTD lower carrying costs and help planners avoid premium expedited freight.
- Durability and handling: The product is hygroscopic; best practices include sealed, dry storage away from light and heat with minimal headspace. Such handling safeguards potency and simplifies inventory rotation.
- User feedback: Fine-chemical and pharma customers value consistent flow properties, quick dissolution, and reproducible redox behavior—attributes that shorten processing time and reduce in-process adjustments.
Sustainability & Market Trends in chemical industry
Sustainability is reshaping the L-cysteine value chain. The market is moving from traditional keratin hydrolysis toward fermentation-based routes that are animal-free and better aligned with ESG goals. Buyers increasingly request traceability, TSE/BSE-free assurances, and reduced environmental impact across the life cycle. At the same time, growth in peptide therapeutics, biologics, and complex generics is lifting global demand for dependable thiol reagents and chiral amino-acid intermediates.
- Regulatory landscape: Emphasis on pharmacopeial alignment, risk management, and robust change control favors suppliers capable of documentation, audits, and responsive technical support.
- Forward-thinking supplier: Hebei Fuyang Biotechnology Co., LTD champions quality, safety, and eco-conscious practices, offering options that support sustainability goals and modern compliance expectations while maintaining competitive performance.
