Structurally, (3S,4R,5R)-4-[(2,4-dichlorophenyl)methoxy]-5-[(2,4-dichlorophenyl)methoxymethyl]-2-methoxy-3-vinyl-tetrahydrofuran-3-ol (C22H22Cl4O5) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 508.22 g/mol, it falls into the moderately-high-molecular-weight range. 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).
