The efficacy of modern antibiotics is a testament to the intricate chemical synthesis processes that yield their active pharmaceutical ingredients (APIs). A pivotal element in the production of Ceftazidime, a crucial third-generation cephalosporin, is the advanced intermediate tert-butyl 2-(((1-(2-aminothiazol-4-yl)-2-(benzo[d]thiazol-2-ylthio)-2-oxoethylidene)amino)oxy)-2-methylpropanoate, identified by CAS number 89604-92-2. Understanding its chemical properties and applications is vital for R&D scientists and procurement specialists in the pharmaceutical sector.

This intermediate, a pale yellow solid, possesses a molecular weight of approximately 478.61 g/mol. Its chemical structure is characterized by a 2-aminothiazole ring coupled with a benzothiazole moiety via a thioester linkage, and it features a BOC-protected isopropoxyiminoacetate functional group. This precise molecular architecture dictates its reactivity and its suitability as a precursor in complex pharmaceutical synthesis. The high purity, typically ≥98.0%, is a critical attribute for its use in API manufacturing, ensuring that the final drug product meets stringent regulatory standards.

The synthesis of this compound involves a carefully controlled series of chemical reactions, often starting from key raw materials. Manufacturers focus on optimizing these processes to achieve high yields and minimal impurities, which directly impacts the cost of the intermediate and, consequently, the final antibiotic. When looking to buy this essential chemical, buyers often search for terms related to 'pharmaceutical intermediate price' and 'manufacturer in China' to find reliable and cost-effective sources.

The primary application of this intermediate lies in the synthesis of Ceftazidime, where it contributes essential structural elements that confer broad-spectrum activity against Gram-negative bacteria. Its role is also significant in the production of Aztreonam, another important antibiotic. For pharmaceutical companies, sourcing this intermediate means securing a consistent supply of a building block that is fundamental to creating these vital medications. Reliable suppliers ensure that this chemical is readily available, supporting the continuous fight against bacterial infections.

In essence, this intermediate embodies the advanced state of pharmaceutical chemical manufacturing. Its detailed chemical properties and successful application underscore the importance of specialized intermediates in producing high-quality, life-saving drugs. Pharmaceutical professionals seeking to enhance their production efficiency and ensure product integrity can find significant value in partnering with expert suppliers of this critical compound.
