Chemical Structure
Description
2-Bromo-4-fluorophenyl trifluoromethanesulfonate (C7H3BrF4O3S) contains a sulfone group, 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, 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).
2-Bromo-4-fluorophenyl trifluoromethanesulfonate (CAS 885276-20-0), molecular formula C7H3BrF4O3S and molecular weight 323.06 g/mol, is a CATO reference standard with documented purity and traceability.
