In the dynamic world of pharmaceutical development, the precise synthesis of active pharmaceutical ingredients (APIs) is paramount. One such crucial compound, serving as a key intermediate, is 1-Cyclohexyl-5-(4-chlorobutyl)-1H-tetrazole, identified by its CAS number 73963-42-5. This molecule is particularly significant in the synthesis pathway of Cilostazol, a drug widely prescribed for its beneficial effects on cardiovascular health, including improving walking distance for patients with intermittent claudication. Its phosphodiesterase III A (PDE3A) inhibitory properties make it a valuable therapeutic agent.

The journey from raw materials to a life-saving medication often involves complex chemical transformations, and intermediates like 1-Cyclohexyl-5-(4-chlorobutyl)-1H-tetrazole are indispensable building blocks. The unique structure of this tetrazole derivative, featuring a tetrazole ring and a functionalized butyl chain, allows for targeted chemical reactions. This versatility makes it a sought-after component in organic synthesis. Manufacturers rely on high-purity intermediates to ensure the efficacy and safety of the final pharmaceutical product. The precise synthesis of 1-Cyclohexyl-5-(4-chlorobutyl)-1H-tetrazole involves carefully controlled reaction conditions, often utilizing reagents such as phosphorus pentachloride and trimethylsilyl azide to construct the critical tetrazole ring structure. Achieving high yields, often reported around 93%, is a testament to optimized production processes.

For pharmaceutical companies and researchers, securing a reliable supply of this intermediate is critical for maintaining consistent production pipelines. China has emerged as a significant hub for the manufacturing of such fine chemicals and pharmaceutical intermediates. Companies specializing in custom synthesis and contract manufacturing in China offer high-quality 1-Cyclohexyl-5-(4-chlorobutyl)-1H-tetrazole, often with purity levels exceeding 95%. These suppliers are adept at meeting the stringent quality standards required by the global pharmaceutical industry. When looking to buy this essential chemical, partnering with a reputable manufacturer in China ensures not only competitive pricing but also a commitment to quality and timely delivery. Understanding the market for chemical building blocks for drugs highlights the importance of these specialized compounds in driving medical advancements. Sourcing this intermediate is a crucial step in the overall strategy for developing and producing effective cardiovascular treatments, underscoring the importance of reliable pharmaceutical intermediate manufacturers.
