Chemical Structure
Description
2-({4-[(Ethylamino)carbonyl]anilino}carbonyl)-benzoic acid 3970AF 945185-45-5 C17H16N2O4 (C17H16N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
