The molecular framework of (4-Methylpiperazin-1-yl)(1-phenyl-3-(pyridin-3-yl)-1H-pyrazol-4-yl)methanone (C20H21N5O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
