Chemical Structure
Description
The molecular framework of 2,6-Bis(3-hydroxyphenyl)pyrrolo[3,4-f]isoindole-1,3,5,7(2H,6H)-tetraone (C22H12N2O6) is characterized by a flavonoid core, an amide 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).
