The molecular framework of N-(4-Chloro-3-(trifluoromethyl)phenyl)-3-(4-(pyridin-3-yloxy)phenyl)-1H-1,2,4-triazol-5-amine (C20H13ClF3N5O) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
