Chemical Structure
Description
CATO supplies 5-(4-Bromophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid (CAS 229957-02-2), a certified reference material (molecular formula C12H6BrF3O3, MW 335.07 g/mol) for analytical method development and quality control.
5-(4-Bromophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid (C12H6BrF3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
As a certified reference material (CRM), 5-(4-Bromophenyl)-2-(trifluoromethyl)furan-3-carboxylic 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.
