Chemical Structure
Description
The occurrence of 2,3,6-Tribromo-5-methylpyridine is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3,6-Tribromo-5-methylpyridine (CAS 393516-82-0), a certified reference material (molecular formula C6H4Br3N, MW 329.81 g/mol) for analytical method development and quality control.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 2,3,6-Tribromo-5-methylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
