Chemical Structure
Description
4-(trifluoromethyl)thiophene-3-carboxylic acid (CAS 767337-60-0), molecular formula C6H7F3O2S and molecular weight 200.18 g/mol, is a CATO reference standard with documented purity and traceability.
4-(trifluoromethyl)thiophene-3-carboxylic acid (C6H7F3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-(trifluoromethyl)thiophene-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.
