Chemical Structure

2-Chloro-8-hydroxy-9,10-dioxo-9,10-dihydroanthracene-1,4-diyl diacetate CAS 87712-28-5 chemical structure

Description

Structurally, 2-Chloro-8-hydroxy-9,10-dioxo-9,10-dihydroanthracene-1,4-diyl diacetate (C18H11ClO7) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine 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 374.73 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).
