Chemical Structure
Description
The molecular framework of 1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)(methyl)amino)-3-(2,6-dichlorobenzyl)-2-methylpyridin-4(1H)-one (C20H15Cl3F3N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
