Chemical Structure

3-(5-{[(3,4-dichlorophenyl)methyl]sulfanyl}-4-ethyl-4H-1,2,4-triazol-3-yl)-1-phenyl-1,4-dihydropyridazin-4-one CAS 478063-60-4 chemical structure

Description

The molecular framework of 3-(5-{[(3,4-dichlorophenyl)methyl]sulfanyl}-4-ethyl-4H-1,2,4-triazol-3-yl)-1-phenyl-1,4-dihydropyridazin-4-one (C21H17Cl2N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
