Chemical Structure

2-Methyl-1H-imidazole-1-carbonitrile CAS 175351-38-9 chemical structure

Description

The molecular framework of 2-Methyl-1H-imidazole-1-carbonitrile (C5H5N3) 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-1H-imidazole-1-carbonitrile (CAS 175351-38-9), molecular formula C5H5N3 and molecular weight 107.11 g/mol, is a CATO reference standard with documented purity and traceability.

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.
