3-(N-Methyl4-fluorobenzenesulfonamido)-thiophene-2-carboxylic acid (CAS 1291486-61-7), molecular formula C12H10FNO4S2 and molecular weight 315.34 g/mol, is a CATO reference standard with documented purity and traceability.
3-(N-Methyl4-fluorobenzenesulfonamido)-thiophene-2-carboxylic acid (C12H10FNO4S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
