Chemical Structure

2,3-Di(1H-pyrrol-2-yl)quinoxalin-5-amine CAS 500190-97-6 chemical structure

Description

Structurally, 2,3-Di(1H-pyrrol-2-yl)quinoxalin-5-amine (C16H13N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 275.31 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).
