Chemical Structure
Description
The molecular framework of 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl methanesulfonate (C17H14O6S) is characterized by a flavonoid core, a sulfone group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
