N-(2,6-dimethylpyrimidin-4-yl)-4-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)benzenesulfonamide (CAS 1024128-19-5), molecular formula C22H18N4O4S and molecular weight 434.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(2,6-dimethylpyrimidin-4-yl)-4-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)benzenesulfonamide (C22H18N4O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 434.47 g/mol, it falls into the moderately-high-molecular-weight range. 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).
CATO manufactures N-(2,6-dimethylpyrimidin-4-yl)-4-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)benzenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
