Description
Compared with other compounds in its class, the molecular weight of 301.13 g/mol gives 3-(5-Bromo-2-fluorophenyl)thiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(5-Bromo-2-fluorophenyl)thiophene-2-carboxylic acid (CAS 1507491-93-1), a certified reference material (molecular formula C11H6BrFO2S, MW 301.13 g/mol) for analytical method development and quality control.
3-(5-Bromo-2-fluorophenyl)thiophene-2-carboxylic acid (C11H6BrFO2S) contains a sulfone group, 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, 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), 3-(5-Bromo-2-fluorophenyl)thiophene-2-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.
