Chemical Structure

(2S,3S,4S,5R,6S)-Methyl 3,4,5-trihydroxy-6-((5-hydroxy-2-(4-hydroxyphenyl)-4-oxo-4H-chromen-7-yl)oxy)tetrahydro-2H-pyran-2-carboxylate CAS 53538-13-9 chemical structure

Description

Owing to a flavonoid core, a hydroxyl group, an ether linkage, (2S,3S,4S,5R,6S)-Methyl 3,4,5-trihydroxy-6-((5-hydroxy-2-(4-hydroxyphenyl)-4-oxo-4H-chromen-7-yl)oxy)tetrahydro-2H-pyran-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 460.39 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).
