Description
As a certified reference material (CRM), 5-Bromo-2-(trifluoromethyl)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
5-Bromo-2-(trifluoromethyl)benzoic acid (CAS 654-97-7) is a high-purity analytical reference standard with the molecular formula C8H4BrF3O2 and a molecular weight of 269.02 g/mol.
5-Bromo-2-(trifluoromethyl)benzoic acid (C8H4BrF3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
