Chemical Structure
Description
CATO supplies 3-Hydroxy-4-(hydroxymethyl)benzoic acid (CAS 74020-82-9), a certified reference material (molecular formula C8H8O4, MW 168.15 g/mol) for analytical method development and quality control.
The molecular framework of 3-Hydroxy-4-(hydroxymethyl)benzoic acid (C8H8O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Hydroxy-4-(hydroxymethyl)benzoic 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.
