Chemical Structure
Description
The occurrence of 3,4-Bis(bromomethyl)pyridine;hydrobromide is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,4-Bis(bromomethyl)pyridine;hydrobromide (CAS 1803611-21-3), a certified reference material (molecular formula C7H7Br2NHBr, MW 345.86 g/mol) for analytical method development and quality control.
Structurally, 3,4-Bis(bromomethyl)pyridine;hydrobromide (C7H7Br2NHBr) contains a nitrile group, 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 345.86 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
