4-Amino-N-(4-methylpyridin-2-yl)benzenesulfonamide (CAS 73497-99-1), molecular formula C12H13N3O2S and molecular weight 263.32 g/mol, is a CATO reference standard with documented purity and traceability.
4-Amino-N-(4-methylpyridin-2-yl)benzenesulfonamide (C12H13N3O2S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
