N-(3-(1H-Benzo[d]imidazol-1-yl)-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-4-nitrobenzenesulfonamide (CAS 1783800-77-0) is a high-purity analytical reference standard with the molecular formula C23H14N4O6S and a molecular weight of 474.45 g/mol.
N-(3-(1H-Benzo[d]imidazol-1-yl)-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-4-nitrobenzenesulfonamide (C23H14N4O6S) contains a flavonoid core, 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).
As a certified reference material (CRM), N-(3-(1H-Benzo[d]imidazol-1-yl)-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-4-nitrobenzenesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
