The molecular framework of 4-(3-Fluoro-4-methylbenzoyl)-3-hydroxy-5-(4-(pentyloxy)phenyl)-1-(pyridin-3-ylmethyl)-1H-pyrrol-2(5H)-one (C29H29FN2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
