5'-Bromo-3-methyl-2,2'-bipyridine CAS 1159281-27-2

Description

Compared with other compounds in its class, the molecular weight of 249.11 g/mol gives 5'-Bromo-3-methyl-2,2'-bipyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5'-Bromo-3-methyl-2,2'-bipyridine (CAS 1159281-27-2), molecular formula C11H9BrN2 and molecular weight 249.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5'-Bromo-3-methyl-2,2'-bipyridine (C11H9BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
