Chemical Structure
Description
N-(2,3-dimethylquinoxalin-6-yl)thiophene-2-sulfonamide (C14H13N3O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
N-(2,3-dimethylquinoxalin-6-yl)thiophene-2-sulfonamide (CAS 672950-10-6), molecular formula C14H13N3O2S2 and molecular weight 319.40 g/mol, is a CATO reference standard with documented purity and traceability.
