Chemical Structure

2-(5-Methyl-1H-pyrazol-3-yl)-1H-benzo[d]imidazole CAS 109073-55-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 198.22 g/mol gives 2-(5-Methyl-1H-pyrazol-3-yl)-1H-benzo[d]imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(5-Methyl-1H-pyrazol-3-yl)-1H-benzo[d]imidazole (CAS 109073-55-4), molecular formula C11H10N4 and molecular weight 198.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-(5-Methyl-1H-pyrazol-3-yl)-1H-benzo[d]imidazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
