Chemical Structure
Description
The molecular framework of 5-Chloro-1-(3-chlorobenzyl)-6-oxo-N-phenyl-1,6-dihydropyridine-3-carboxamide (C19H14Cl2N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Chloro-1-(3-chlorobenzyl)-6-oxo-N-phenyl-1,6-dihydropyridine-3-carboxamide (CAS 338977-38-1) is a high-purity analytical reference standard with the molecular formula C19H14Cl2N2O2 and a molecular weight of 373.23 g/mol.
