N-(4-(N-(2-(6-Oxo-3-phenylpyridazin-1(6H)-yl)ethyl)sulfamoyl)phenyl)propionamide (CAS 921535-32-2) is a high-purity analytical reference standard with the molecular formula C21H22N4O4S and a molecular weight of 426.49 g/mol.
The molecular framework of N-(4-(N-(2-(6-Oxo-3-phenylpyridazin-1(6H)-yl)ethyl)sulfamoyl)phenyl)propionamide (C21H22N4O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
