L Cysteine Hydrochloride Monohydrate Overview
L Cysteine Hydrochloride Monohydrate (CAS 7048-04-6) is the hydrochloride salt of the sulfur-containing amino acid L-cysteine with one molecule of crystallization water. Also known as cysteine hydrochloride monohydrate, l cysteine HCl monohydrate, or cysteine HCl monohydrate, it appears as a white to off-white crystalline powder that is freely soluble in water. With a molecular formula of C3H7NO2S·HCl·H2O and a molecular weight of approximately 175.63 g/mol, it is prized in fine chemicals and pharmaceutical raw materials and intermediates for its reducing capability, chiral purity, and process reliability. Typical quality expectations include high assay, low heavy metals, and tight control of bioburden and endotoxin for sensitive applications.
For B2B buyers, consistency and traceability are paramount. Hebei Fuyang Biotechnology Co., LTD supports these needs with robust quality management, full batch documentation (COA, MSDS, traceability), and stable supply planning. In a recent project with a peptide-focused manufacturer, upgrading to a tighter-spec L Cysteine Hydrochloride Monohydrate helped streamline downstream purification by minimizing oxidative by-products, illustrating how reliable inputs reduce deviations and unlock better yields in cGMP environments.

Benefits & Use Cases of L Cysteine Hydrochloride Monohydrate in Pharmaceutical raw materials and intermediates
As a versatile pharmaceutical intermediate, L Cysteine Hydrochloride Monohydrate plays several roles across API, peptide, and bioprocess workflows. It is widely used in peptide synthesis as a chiral amino acid building block and as a reducing agent to manage disulfide bonds, supporting correct folding and minimizing oxidative impurities. In API/intermediate routes, it serves as a precursor for sulfur-containing actives and derivatives (e.g., N-acetylcysteine) and as a nucleophile in selective transformations. In bioprocessing, cysteine hydrochloride monohydrate is included in cell-culture and fermentation media to sustain growth and manage redox balance. It also functions as an antioxidant/reducing excipient in certain dosage forms where permitted by the relevant regulations.
Competitive advantages for B2B buyers include strong aqueous solubility for easy charge-in, reliable chiral purity, and predictable performance in sensitive synthesis steps. Hebei Fuyang Biotechnology Co., LTD emphasizes lot-to-lot consistency, impurity control, and comprehensive supporting documentation to simplify vendor qualification.
