Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, .beta.-D-Glucopyranose, cyclic 4.fwdarw.2':6.fwdarw.2-[(1S)-4-(6-carboxy-2,3,4-trihydroxyphenoxy)-4',5,5',6,6'-pentahydroxy[1,1'-biphenyl]-2,2'-dicarboxylate] 1,2,3-tris(3,4,5-trihydroxybenzoate), 2-ester with .beta.-D-glucopyranose 1,3,6-tris(3,4,5-trihydroxybenzoate) 127243-65-6 Woodfordin A [(2S,3R,4S,5R,6R)-5-hydroxy-2,4-bis[(3,4,5-trihydroxybenzoyl)oxy]-6-[(3,4,5-trihydroxybenzoyl)oxymethyl]tetrahydropyran-3-yl] 3,4,5-trihydroxy-2-[pentahydroxy-dioxo-tris[(3,4,5-trihydroxybenzoyl)oxy][?]yl]oxy-benzoate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1725.22 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).
