Chemical Structure
Description
The occurrence of 3-Difluoromethanesulfonylthiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Difluoromethanesulfonylthiophene-2-carboxylic acid (CAS 1269151-66-7), molecular formula C6H4F2O4S2 and molecular weight 242.22 g/mol, is a CATO reference standard with documented purity and traceability.
3-Difluoromethanesulfonylthiophene-2-carboxylic acid (C6H4F2O4S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
