Chemical Structure
Description
Structurally, (Z)-4-(((E)-3-(2-(((4-Bromobenzyl)oxy)carbonyl)-3-hydroxy-5-methoxyphenyl)allyl)amino)-4-oxobut-2-enoic acid (C22H20BrNO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 490.30 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).
