Chemical Structure
Description
The molecular framework of 2-((3-Oxo-2-(3,4,5-trimethoxybenzylidene)-2,3-dihydrobenzofuran-6-yl)oxy)acetic acid (C20H18O8) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
