In the realm of chemical synthesis, certain molecular building blocks stand out for their versatility and importance. D-Cysteine, identified by its CAS number 921-01-7, is one such compound. As a non-natural isomer of the proteinogenic amino acid L-cysteine, D-Cysteine offers unique chemical properties that make it a valuable intermediate for a wide range of synthetic applications. For procurement managers and research scientists, understanding where and how to source this compound reliably is key.

D-Cysteine is typically supplied as a white crystalline powder, with high purity levels often exceeding 99%. This high purity is critical for many chemical reactions, particularly in the pharmaceutical and specialty chemical sectors, where impurities can lead to failed syntheses or affect the final product’s characteristics. When seeking to buy d-cysteine pharmaceutical intermediate, looking for suppliers with robust quality control, such as those offering high purity d-cysteine powder, is essential. Companies frequently compare the d-cysteine cas 921-01-7 price to ensure they are getting the best value for their investment.

The thiol (-SH) group in D-Cysteine is particularly reactive, participating in disulfide bond formation, Michael additions, and nucleophilic substitutions. The amino and carboxyl groups also offer sites for derivatization, allowing chemists to incorporate D-Cysteine into complex peptide structures, heterocycles, or chiral ligands. Its applications extend beyond pharmaceuticals; it's used in biochemical research to study enzyme mechanisms, probe metabolic pathways, and investigate the biological roles of D-amino acids. For researchers, finding a reliable d-cysteine supplier is paramount for uninterrupted experimentation.

Many leading chemical companies in China serve as prominent d-cysteine manufacturers, catering to global demand. These manufacturers often offer competitive pricing and a consistent supply chain, making them an attractive option for bulk purchasing. By establishing a relationship with a reputable Chinese supplier, businesses can ensure a steady flow of high-quality D-Cysteine for their ongoing projects. The efficiency and scale of production in China contribute significantly to the accessibility and affordability of this important chemical intermediate.
