Chemical Structure
Description
Structurally, 2,4-Diiodo-1-methyl-1H-imidazole (C4H4I2N2) contains a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 333.90 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).
