Chemical Structure
Description
Structurally, 3-Bromo-4-chloro-5-iodopyridine (C5H2BrClIN) contains a nitrile group, chlorine/bromine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 318.34 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).
