The pharmaceutical industry thrives on precision and the meticulous selection of chemical building blocks. For the production of Cefdinir, a vital third-generation cephalosporin antibiotic, a key intermediate, S-2-Benzothiazolyl (Z)-2-(2-aminothiazol-4-yl)-2-trityloxyiminoethanethioate (CAS 143183-03-3), plays a central role. Understanding this compound's properties and its sourcing is paramount for pharmaceutical intermediate manufacturers and companies relying on a steady supply of cefdinir raw material.

This intermediate, with its complex chemical name and structure, is characterized by its off-white to light yellow crystalline powder appearance and a high purity level of typically ≥98.0%. These attributes are critical for ensuring the success of cefdinir active ester synthesis, as they minimize the presence of unwanted byproducts and contaminants. The precise molecular formula (C31H22N4O2S3) and molecular weight (578.72700) provide chemists with essential data for reaction planning and optimization.

As a leading pharmaceutical intermediate manufacturer, we emphasize the importance of reliable sourcing for critical compounds like this. Companies seeking to procure this Cefdinir active ester should partner with established fine chemical sourcing specialists or dedicated intermediate manufacturers. Such partners can ensure not only the required purity but also provide vital technical support and documentation, including MSDS and COAs. Securing a consistent supply of this high-quality Cefdinir intermediate is fundamental for any pharmaceutical company engaged in the production of this essential antibiotic, contributing directly to the efficiency and integrity of the API manufacturing process.
