1-[(3,4-Dichlorophenyl)methyl]-5-(4-phenylpiperazine-1-carbonyl)-1,2-dihydropyridin-2-one (CAS 242472-02-2), molecular formula C23H21Cl2N3O2 and molecular weight 442.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(3,4-Dichlorophenyl)methyl]-5-(4-phenylpiperazine-1-carbonyl)-1,2-dihydropyridin-2-one (C23H21Cl2N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
