For procurement professionals and R&D scientists in the chemical and pharmaceutical industries, a thorough understanding of product specifications is fundamental. 5-Aminobenzimidazole (CAS 934-22-5) is no exception. Knowing its key characteristics, quality parameters, and manufacturing standards ensures that you are sourcing the right material for your intended applications and can negotiate effectively with suppliers.

Chemical Identity and Purity of 5-Aminobenzimidazole

5-Aminobenzimidazole, also known by its CAS number 934-22-5, is identified by its molecular formula C7H7N3 and a molecular weight of 133.15 g/mol. Its physical form is typically described as a powder to crystal, with a color ranging from light yellow to brown. Crucially, for its use as a pharmaceutical intermediate, high purity is often required. Suppliers typically specify purity levels based on analytical techniques such as HPLC or GC, with common requirements being >98% or even higher for specific applications. When you buy 5-Aminobenzimidazole, always request the Certificate of Analysis (CoA) to verify these purity levels.

Adherence to Quality Standards

Reputable manufacturers and suppliers often ensure that their 5-Aminobenzimidazole meets pharmacopoeial standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), and FCC (Food Chemicals Codex). Adherence to these standards indicates rigorous quality control throughout the manufacturing process, from raw material sourcing to final product testing. This is particularly important if your downstream products are intended for human or animal use, or if they require very high levels of purity to avoid interference in sensitive reactions.

Physical Properties and Handling

Understanding the physical properties of 5-Aminobenzimidazole is also important for handling and storage. Its melting point is typically in the range of 163-168 °C. While solubility information might vary, it is generally described as slightly soluble in methanol. Storage recommendations often include keeping it in a dark place and under an inert atmosphere at room temperature to maintain its stability. For large-scale procurement, understanding the available packaging options, such as 25kg drums, is also essential.

When sourcing CAS 934-22-5, engaging with manufacturers who provide comprehensive technical data sheets (TDS) and safety data sheets (SDS) alongside their product quotes can streamline your evaluation process.
