Chemical Structure
Description
The molecular framework of 4'-Formyl-3-methoxy-[1,1'-biphenyl]-4-carboxylic acid (C15H12O4) 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).
