Chemical Structure
Description
2-(4-Chlorophenyl)-2-oxoethyl 2-acetamido-2-[(4-methoxyphenyl)carbamoyl]acetate (C20H19ClN2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
