Chemical Structure
Description
The occurrence of 3,5-Dibromo-4-chloro-2,6-dimethylpyridine is closely related to a nitrile group, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-Dibromo-4-chloro-2,6-dimethylpyridine (CAS 633318-46-4) is a high-purity analytical reference standard with the molecular formula C7H6Br2ClN and a molecular weight of 299.39 g/mol.
The molecular framework of 3,5-Dibromo-4-chloro-2,6-dimethylpyridine (C7H6Br2ClN) is characterized by a nitrile group, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
