Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-((4,5-Dimethoxy-3-oxo-1,3-dihydroisobenzofuran-1-yl)amino)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
