Description
CATO supplies 3-(Hydroxymethyl)-5-methylbenzoic acid (CAS 63440-59-5), a certified reference material (molecular formula C9H10O3, MW 166.17 g/mol) for analytical method development and quality control.
3-(Hydroxymethyl)-5-methylbenzoic acid (C9H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-(Hydroxymethyl)-5-methylbenzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
