Chemical Structure
Description
N-(2,5-dimethoxyphenyl)-3-(4-fluoro-2-nitrophenoxy)thiophene-2-carboxamide (C19H15FN2O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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).
