Cephalosporin antibiotics represent a cornerstone in modern medicine's fight against bacterial infections. The efficient and high-yield Active Pharmaceutical Ingredient (API) development of these drugs is crucial for global health. A key raw material significantly impacting this process is AE-Active Ester, also known as S-2-Benzothiazolyl 2-amino-alpha-(methoxyimino)-4-thiazolethiolacetate, identified by its CAS 80756-85-0.


This advanced pharmaceutical intermediate plays a vital role in the complex multi-step synthesis of various cephalosporins, notably Ceftriaxone and Cefotaxime. Its exceptional purity and consistent quality are paramount, as they directly influence the purity profile and yield of the final antibiotic API. Optimizing the use of AE-Active Ester allows for streamlined synthetic pathways, reducing reaction times and minimizing waste, which are critical considerations in large-scale production.


Manufacturers focused on Ceftriaxone intermediate development or Cefotaxime synthesis raw material often seek suppliers that not only provide the product but also understand its chemical behavior and application intricacies. A reliable AE-active ester supplier can offer technical support and consistent supply, which are invaluable for continuous API development and commercialization. The ability to source a high purity AE-active ester is a significant advantage, ensuring that downstream processes are efficient and the final drug meets stringent regulatory standards.
