Chemical Structure

4-(2-Oxo-2H-chromen-3-yl)benzoic acid CAS 14071-70-6 chemical structure

Description

The molecular framework of 4-(2-Oxo-2H-chromen-3-yl)benzoic acid (C16H10O4) is characterized by a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
