Chemical Structure
Description
The molecular framework of Pyridine (3-oxo-1,3-dihydroiSobenzofuran-1,1-diyl)bis(4,1-phenylene) bis(phosphate) (C20H16O10P2C5H5N) is characterized by a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
