Chemical Structure

(2R,3R,4R,5R,6S)-5-acetamido-2-(acetoxymethyl)-6-(benzyloxy)tetrahydro-2H-pyran-3,4-diyl diacetate CAS 141019-71-8 chemical structure

Description

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2R,3R,4R,5R,6S)-5-acetamido-2-(acetoxymethyl)-6-(benzyloxy)tetrahydro-2H-pyran-3,4-diyl diacetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.44 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).
