Chemical Structure
Description
Structurally, 3-Bromo-5-chloro-4-(chloromethyl)pyridine hydrochloride (C6H4BrCl2NHCl) contains a nitrile group, chlorine/bromine 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 277.37 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).
