For professionals in the chemical industry, understanding the detailed specifications of a product like Isovanillin (CAS 621-59-0) is fundamental to making informed purchasing decisions. Isovanillin, a vital intermediate used in flavors, fragrances, and pharmaceuticals, must meet rigorous quality criteria to ensure its effective performance in various applications. This guide provides a focused look at the key specifications that buyers should consider when sourcing this compound.

The most critical specification for Isovanillin is its assay, which indicates its purity. Reputable manufacturers typically guarantee a minimum assay of 99.5%. This high level of purity is essential, especially when Isovanillin is used as a pharmaceutical intermediate, where even minor impurities can affect the efficacy and safety of the final drug product. Another key characteristic is its appearance: a light yellow crystalline powder. Deviations from this description could signal issues with the manufacturing process or product degradation.

Furthermore, compliance with recognized industry standards is paramount. Buyers should confirm that the Isovanillin they intend to buy meets standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), EP (European Pharmacopoeia), and FCC (Food Chemicals Codex). These certifications assure that the product has undergone stringent testing for quality, purity, and safety. When you purchase Isovanillin, always request a Certificate of Analysis (CoA) that details these specifications for the specific batch being supplied.

For businesses looking to secure a reliable supply, identifying a quality manufacturer and supplier is crucial. When considering a supplier in China, it is advisable to inquire about their quality management systems and production processes. Comparing pricing from multiple vendors is also important, but it should always be balanced against the assurance of quality and compliance. Understanding these specifications empowers buyers to make confident purchasing decisions and to ensure they are acquiring Isovanillin that meets their exact needs.
