Chemical Structure

2-methyl-3H-imidazo[4,5-b]pyridine CAS 68175-07-5 chemical structure

Description

The molecular framework of 2-methyl-3H-imidazo[4,5-b]pyridine (C7H15N3) is characterized by a nitrile group. 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.

2-methyl-3H-imidazo[4,5-b]pyridine (CAS 68175-07-5) is a high-purity analytical reference standard with the molecular formula C7H15N3 and a molecular weight of 141.21 g/mol.

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.
