Description
Compared with other compounds in its class, the molecular weight of 235.10 g/mol gives 5-Bromo-2,4-dimethylthiophene-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromo-2,4-dimethylthiophene-3-carboxylic acid (CAS 503308-97-2), a certified reference material (molecular formula C7H7BrO2S, MW 235.10 g/mol) for analytical method development and quality control.
5-Bromo-2,4-dimethylthiophene-3-carboxylic acid (C7H7BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
CATO manufactures 5-Bromo-2,4-dimethylthiophene-3-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.
