Chemical Structure
Description
The molecular framework of Ethyl 3-(1-(3,4-dimethoxyphenyl)-5-oxopyrrolidine-3-carboxamido)benzoate (C22H24N2O6) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
