Chemical Structure
Description
CATO supplies 2,3-Dibromo-6-hydroxy-4-methoxybenzofuran-5-carboxylic acid (CAS 88258-48-4), a certified reference material (molecular formula C10H6Br2O5, MW 365.96 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2,3-Dibromo-6-hydroxy-4-methoxybenzofuran-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2,3-Dibromo-6-hydroxy-4-methoxybenzofuran-5-carboxylic 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.
