In the pharmaceutical sector, quality is not just a buzzword; it is the foundation of trust and efficacy. Every component, from the smallest excipient to the most complex API, must meet rigorous standards. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to upholding these standards by providing high-purity pharmaceutical intermediates. A prime example is (2S-cis)-(+)-2,3-Dihydro-3-hydroxy-2-(4-methoxyphenyl)-1,5-benzothiazepin-4(5H)-one, identified by CAS number 42399-49-5, a vital intermediate in the synthesis of Diltiazem hydrochloride.

The designation CAS 42399-49-5 represents more than just an identifier; it signifies a specific chemical entity with crucial properties for pharmaceutical manufacturing. This compound, presented as an off-white crystalline powder, boasts a molecular formula of C16H15NO3S and a molecular weight of 301.36 g/mol. For manufacturers of Diltiazem, the purity of this intermediate is paramount. Our product guarantees a minimum assay of 98.0%, ensuring that the synthesis process is efficient and the resulting API is free from significant impurities. This focus on purity is a critical aspect of our commitment to our clients, enabling them to produce safe and effective medications.

The specific (2S-cis) stereochemistry of this benzothiazepinone derivative is what makes it indispensable for Diltiazem synthesis. Achieving the correct enantiomeric form is crucial for the drug's pharmacological activity. NINGBO INNO PHARMCHEM CO.,LTD. ensures precise stereochemical control in our manufacturing processes, making us a trusted source for this critical hydroxy lactam. By partnering with NINGBO INNO PHARMCHEM CO.,LTD., pharmaceutical companies can be confident in the quality and reliability of their raw materials, contributing to the overall integrity and success of their Diltiazem production efforts.
