In the demanding pharmaceutical sector, the procurement of high-purity intermediates is a cornerstone of drug development and manufacturing. For companies specializing in cardiovascular therapies, cis-4-Phenylthio-L-proline Hydrochloride (CAS: 105107-84-4) stands out as a critical raw material. This article is designed for procurement managers and R&D scientists who need to understand the intricacies of sourcing this vital compound, particularly from leading manufacturers in China.

The chemical, cis-4-Phenylthio-L-proline Hydrochloride, is characterized by its white powder appearance and a guaranteed assay of ≥98.0%. This level of purity is crucial as it directly impacts the yield and quality of the final Active Pharmaceutical Ingredient (API), Zofenopril calcium. The molecular formula C11H14ClNO2S and molecular weight 259.752 are standard specifications, but the consistency and reliability of supply are what truly differentiate suppliers in this market. As a dedicated manufacturer, we ensure that every batch we produce adheres to these strict specifications.

The primary application of cis-4-Phenylthio-L-proline Hydrochloride is as a key intermediate in the synthesis of Zofenopril calcium (CAS: 81938-43-4). This drug is a cornerstone in the management of hypertension and other cardiovascular conditions. The stereospecific synthesis of Zofenopril relies heavily on the precise structure of its precursors. Therefore, securing a high-quality, enantiomerically pure intermediate is not just a matter of cost but of therapeutic efficacy and patient safety. When you are looking to buy this product, prioritizing suppliers with robust quality assurance is essential.

China has established itself as a global powerhouse in chemical manufacturing, offering a wide array of pharmaceutical intermediates.
