Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 186.05 g/mol gives 4-(Bromomethyl)-2-methylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Bromomethyl)-2-methylpyridine (CAS 1167055-68-6), a certified reference material (molecular formula C7H8BrN, MW 186.05 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Bromomethyl)-2-methylpyridine (C7H8BrN) is characterized by a nitrile group, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
