Chemical Structure

4,6-Dimethyl-3H-imidazo[4,5-c]pyridine CAS 18233-01-7 chemical structure

Description

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.

4,6-Dimethyl-3H-imidazo[4,5-c]pyridine (CAS 18233-01-7), molecular formula C8H9N3 and molecular weight 147.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H9N3, 4,6-Dimethyl-3H-imidazo[4,5-c]pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 147.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
