D-Cysteine hydrochloride

Product Overview

D-Cysteine hydrochloride is a critical chiral amino acid derivative extensively utilized in the pharmaceutical and fine chemical industries. As the D-enantiomer of cysteine, this compound serves as an essential building block for the synthesis of complex organic molecules, particularly in the development of beta-lactam antibiotics and specialized peptide sequences. Our manufacturing process ensures exceptional stereochemical purity, making it an ideal choice for researchers and production facilities requiring reliable chiral sources.

We understand the stringent demands of modern drug development. Therefore, our D-Cysteine hydrochloride is produced under rigorous quality management systems to guarantee consistency across batches. The compound is supplied as a stable hydrochloride salt, which enhances its handling properties and solubility in various synthetic routes. Whether used for nucleophilic substitution reactions or as a sulfur source in heterocyclic synthesis, this material delivers predictable performance.

Technical Specifications

Quality is the cornerstone of our supply chain. Each batch undergoes comprehensive analytical testing to verify compliance with international standards. The following table outlines the key physical and chemical parameters guaranteed for this product:

Industrial Applications

The primary application of D-Cysteine hydrochloride lies in the synthesis of pharmaceutical intermediates. It is notably used in the production of Cefminox sodium, a cephalosporin antibiotic, where the chiral integrity of the cysteine moiety is vital for biological activity. Beyond antibiotics, this compound is valuable in the preparation of peptide mimetics and radiopharmaceuticals where sulfur-containing amino acids are required.

Chemists value this material for its reactivity in thiol-based conjugation reactions. The free sulfhydryl group, protected in the salt form until deprotonation, allows for controlled participation in disulfide bond formation or metal coordination complexes. This versatility makes it a staple in medicinal chemistry laboratories focused on structure-activity relationship studies.

Quality Assurance and Logistics

We maintain a robust quality assurance protocol that includes raw material screening, in-process controls, and final product verification. A Certificate of Analysis (COA) is provided with every shipment, detailing the specific test results for the batch received. Our facility adheres to strict safety and environmental standards, ensuring that the manufacturing process minimizes impurities such as heavy metals and residual solvents.

For storage, we recommend keeping the container tightly closed in a cool, dry, and well-ventilated area to prevent moisture absorption and oxidation. The product is typically packaged in 25kg drums, though we offer flexible packaging solutions to meet specific customer requirements. Our global logistics network ensures timely delivery while maintaining the integrity of the chemical during transit.
