Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution, (2S,3S,4S,5R,6S)-6-((6,8-difluoro-4-methyl-2-oxo-2H-chromen-7-yl)oxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.27 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).
