2-({[4-chloro-2-(trifluoromethyl)phenyl]carbamoyl}methanesulfonyl)acetic acid (CAS 344275-38-3), molecular formula C11H9ClF3NO5S and molecular weight 359.71 g/mol, is a CATO reference standard with documented purity and traceability.
2-({[4-chloro-2-(trifluoromethyl)phenyl]carbamoyl}methanesulfonyl)acetic acid (C11H9ClF3NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
