For any procurement manager, R&D scientist, or formulation chemist, understanding the precise specifications of a chemical compound is fundamental to successful purchasing and application. This is particularly true for critical intermediates like 3,4-Dihydroxybenzaldehyde (CAS 139-85-5), a compound vital for pharmaceutical, cosmetic, and chemical industries. As a prominent manufacturer and supplier, we aim to demystify these specifications to help you buy with confidence.

The most crucial specification for 3,4-Dihydroxybenzaldehyde is its purity. Typically, in applications requiring high performance, such as pharmaceutical synthesis, a purity of ≥99% as determined by High-Performance Liquid Chromatography (HPLC) is considered standard. This high purity ensures that side reactions are minimized and that the final synthesized product meets stringent quality controls. When you buy this intermediate, always verify the assay method and percentage provided by your supplier.

Beyond purity, other important parameters include its physical appearance, which is commonly described as a light grey, light brown, or off-white crystalline powder. The melting point, typically in the range of 153-159 °C, is another indicator of its quality. Molecular formula (C7H6O3) and molecular weight (138.12 g/mol) are standard identifiers that confirm the compound's identity.

When considering a purchase, it’s important to look at the supplier’s commitment to quality assurance. Reputable manufacturers provide Certificates of Analysis (COA) for each batch, detailing the specific test results for purity, appearance, and other key parameters. For international buyers, understanding Certificates of Origin (COO) is also important for customs and trade compliance. We, as a leading supplier in China, are committed to providing comprehensive documentation to support your procurement needs.
