Chemical Structure

8-Methyl-11(H)-benzo[a]carbazole CAS 21064-33-5 chemical structure

Description

Structurally, 8-Methyl-11(H)-benzo[a]carbazole (C17H13N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 231.29 g/mol, it falls into the medium-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).
