For businesses operating within the pharmaceutical and fine chemical sectors, the reliable procurement of essential intermediates is fundamental to success. 3-Hydroxy-5-mercapto-4-isothiazolecarboxylic acid monosodium salt, identified by CAS number 475112-25-5 and often abbreviated as HMIM, is one such critical compound, primarily utilized in the synthesis of the antibiotic cefotetan. This guide aims to assist procurement professionals and research scientists in understanding the key aspects of sourcing this valuable chemical.

When initiating the process to buy HMIM, it is essential to establish clear requirements. This includes specifying the desired purity level, typically ≥98.0%, and confirming the physical form, which is commonly an off-white to white crystalline powder. Understanding the compound's chemical identity – its molecular formula (C4H2NNaO3S2) and weight (199.18300) – ensures alignment with your project's technical needs.

Identifying a suitable supplier is a critical step. For procurement managers looking for competitive pricing and robust supply chains, exploring manufacturers in regions like China is common. However, selecting a reliable manufacturer of HMIM requires due diligence. Key factors to assess include their production capacity, adherence to quality standards, and their ability to provide comprehensive documentation such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS).

Consider the overall service offered by potential suppliers. A responsive customer service team that can provide quotes promptly and offer technical support adds significant value. For those involved in the synthesis of cefotetan, sourcing HMIM from a trusted partner ensures the continuity and quality of their production pipeline. Whether you are a research scientist exploring new applications or a procurement manager managing bulk orders for a cefotetan synthesis intermediate, a strategic approach to procurement will yield the best results.
