Omeprazole Sulfide (CAS 73590-85-9) is a compound of significant interest within the pharmaceutical chemistry sector. Its primary role as a synthetic intermediate for proton pump inhibitors (PPIs) like Omeprazole and Esomeprazole, coupled with its classification as Omeprazole Impurity C, makes it a compound of dual importance. For professionals in R&D and manufacturing, understanding its synthesis and applications is key to leveraging its potential.

The synthesis of Omeprazole Sulfide typically involves the reaction between 2-mercapto-5-methoxybenzimidazole and a derivative of 2-chloromethyl-4-methoxy-3,5-dimethylpyridine. This chemical transformation, often carried out under controlled conditions by specialized manufacturers, yields the target molecule with its characteristic benzimidazole and pyridine rings linked by a thioether bond. The process requires precise control over reaction parameters to achieve high yields and the desired purity, often exceeding 97% as specified by reputable suppliers.

The applications of Omeprazole Sulfide are largely centered around its utility in the pharmaceutical industry. As a pharmaceutical intermediate, it serves as a crucial building block. Procurement managers looking to buy Omeprazole Sulfide for bulk synthesis can rely on manufacturers for consistent quality and supply. The compound's well-defined physical and chemical properties, such as its white powder appearance and melting point of 115-119°C, are essential for batch-to-batch consistency in large-scale API production.

Beyond its role as a synthetic precursor, Omeprazole Sulfide is indispensable as a reference standard in pharmaceutical quality control. Its presence as Omeprazole Impurity C necessitates its availability as a characterized material for analytical methods, such as HPLC. This allows researchers and quality assurance teams to accurately identify and quantify this specific impurity in drug formulations, ensuring product safety and efficacy.

For those seeking to purchase Omeprazole Sulfide, engaging with established manufacturers, particularly those based in China, offers benefits such as competitive pricing and access to extensive chemical synthesis expertise. The availability of detailed technical data, including molecular formula, molecular weight, and safety information, is a testament to a supplier's commitment to product transparency and quality.

In conclusion, Omeprazole Sulfide (CAS 73590-85-9) is a multifaceted compound vital to the pharmaceutical landscape. Its strategic importance as both a synthetic intermediate and a reference standard underscores the need for reliable sourcing from experienced manufacturers. Understanding its synthesis and application allows for its effective utilization in drug development and production.
