Chemical Structure
Description
The molecular framework of (4Z,7Z,10Z,13E,15E,19Z)-17-Hydroxydocosa-4,7,10,13,15,19-hexaenoic acid (C22H32O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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).
