Chemical Structure
Description
The molecular framework of (5Z,13E,15S)-2,2-Difluoro-9alpha,11alpha,15-Trihydroxy-15-Methylprosta-5,13-Dien-1-Oic Acid 1,9-Lactone (C21H32F2O4) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine 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. 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).
