Description
CATO manufactures 5-Bromo-2-hydroxy-3-(trifluoromethyl)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.
5-Bromo-2-hydroxy-3-(trifluoromethyl)benzoic acid (CAS 251300-31-9) is a high-purity analytical reference standard with the molecular formula C8H4BrF3O3 and a molecular weight of 285.01 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 5-Bromo-2-hydroxy-3-(trifluoromethyl)benzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.01 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.
