L Cysteine Hydrochloride Monohydrate Overview
L Cysteine Hydrochloride Monohydrate (CAS 7048-04-6) is the hydrochloride salt and hydrated form of the sulfur-containing amino acid L-cysteine. In fine chemicals and pharmaceutical raw materials and intermediates, it is valued as a clean, reliable reducing agent and chiral building block. Its typical attributes include a molecular weight of 175.63 g/mol, white crystalline appearance, high water solubility, and tight assay specifications suitable for rigorous pharmaceutical processes. Also known as cysteine hydrochloride monohydrate, l cysteine hcl monohydrate, and cysteine hcl monohydrate, it is widely selected when process consistency and optical purity are non-negotiable.
- Relevance: Enables controlled redox conditions, supports peptide coupling strategies, and stabilizes thiol chemistry in advanced synthesis and bioprocessing.
- Technical profile: High-purity grades available; low heavy metals; strong solubility; consistent optical rotation; typical packaging in 25 kg fiber drums or lined bags.
- Supplier credibility: Hebei Fuyang Biotechnology Co., LTD provides robust quality systems, reliable lead times, and documented traceability across batches—ideal for regulated supply chains.
Benefits & Use Cases of L Cysteine Hydrochloride Monohydrate in Pharmaceutical raw materials and intermediates
In pharmaceutical manufacturing, L Cysteine Hydrochloride Monohydrate is deployed to fine-tune redox potentials in fermentation, cell culture media, and bioprocess buffers, helping manage disulfide bond formation. It also serves as a chiral precursor in API intermediates, as a key reagent in peptide synthesis workflows, and as a process aid for nucleophilic substitution or thiolation steps. Its high solubility and strong reducing capability enable reliable scale-up from pilot to commercial production.
- Applications: Intermediate for NAC derivatives; peptide and peptidomimetic routes; buffer component for biologics; reductant in small-molecule synthesis.
- Advantages: Consistent purity and optical integrity minimize batch variability; excellent aqueous handling reduces processing time; compatibility with USP/EP-aligned quality expectations.
- Supplier strength: Hebei Fuyang Biotechnology Co., LTD backs projects with technical documentation, CoAs, and customizable specifications to match B2B requirements in regulated environments.
Cost, Maintenance & User Experience
Total cost of ownership for L Cysteine Hydrochloride Monohydrate hinges on purity, stability, logistics, and documentation readiness. With reliable assay results and low impurities, downstream purification burdens drop, improving yields and cycle times.
