Chemical Structure
Description
The occurrence of 3-Bromo-2,4,6-trimethylpyridine is closely related to a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-2,4,6-trimethylpyridine (CAS 23079-73-4), molecular formula C8H10BrNHCl and molecular weight 236.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-2,4,6-trimethylpyridine (C8H10BrNHCl) is characterized by a nitrile group, chlorine/bromine substitution. 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
