Chemical Structure
Description
The molecular framework of 1-(2-((2-((2-(2-oxo-2,5-Dihydro-1H-pyrrol-1-yl)phenyl)thio)ethyl)thio)phenyl)-1H-pyrrole-2,5-dione (C22H16N2O4S2) is characterized by a flavonoid core, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
