For procurement specialists and R&D chemists in the pharmaceutical sector, sourcing high-purity chemical intermediates is a critical step in drug development and manufacturing. 1,2-Benzisothiazol-3(2H)-one, identified by CAS number 2634-33-5, is a key intermediate, particularly for the synthesis of the antipsychotic medication Ziprasidone. Understanding where and how to buy this compound effectively can significantly impact project timelines and product quality.

When you need to buy 1,2-Benzisothiazol-3(2H)-one, the primary consideration is purity. Manufacturers often specify a purity level of ≥98%, ensuring that the intermediate is suitable for demanding pharmaceutical applications. This compound, typically appearing as a white or light yellow powder, serves as a crucial precursor in the synthesis of Ziprasidone hydrochloride and mesilate. Therefore, the quality of the supplied intermediate directly influences the final API's specifications.

Identifying reputable manufacturers and suppliers is essential for a smooth procurement process. Companies looking to buy this intermediate often turn to global suppliers, including those based in China, who specialize in pharmaceutical chemicals. These manufacturers are typically capable of producing the compound at scale and can offer competitive pricing. When making an inquiry, it is advisable to request a detailed quotation, inquire about minimum order quantities (MOQ), and ask for a Certificate of Analysis (CoA) to verify the product’s specifications.

The process of purchasing 1,2-Benzisothiazol-3(2H)-one for your Ziprasidone synthesis projects should involve evaluating the supplier's reliability and technical support. A good partner will not only provide the chemical but also offer insights into handling, storage, and any regulatory compliance requirements. Building a relationship with a trusted chemical supplier ensures a consistent and dependable supply chain, which is vital for continuous pharmaceutical production. Many suppliers provide easy-to-use online portals to facilitate your purchase inquiries and orders.

In summary, if you are looking to buy high-purity 1,2-Benzisothiazol-3(2H)-one, focus on manufacturers and suppliers who can guarantee ≥98% purity and offer consistent quality. By leveraging the capabilities of experienced chemical producers and conducting thorough due diligence, you can secure this essential intermediate for your pharmaceutical R&D and manufacturing needs, ultimately supporting the production of vital medicines.
