Chemical Structure
Description
Structurally, 2,3-Dichloro-6-iodoquinoxaline (C8H3Cl2IN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 324.93 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).
