Chemical Structure
Description
The molecular framework of 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 2-(4-chlorophenoxy)-2-methylpropanoate (C18H14ClNO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
