Chemical Structure

ethyl (9E,12Z)-octadeca-9,12-dienoate CAS CATO-C4X-289045 chemical structure

Description

The molecular framework of ethyl (9E,12Z)-octadeca-9,12-dienoate (C20H36O2) is characterized by a carboxylic acid group, 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).
