Chemical Structure
Description
The molecular framework of 4-[(2E)-3-(3-Chlorophenyl)prop-2-enoyl]phenyl 4-chlorobenzoate (C22H14Cl2O3) is characterized by a steroid core, a hydroxyl group, an ether linkage, 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.
