Chemical Structure

1H-imidazol-2-ylacetonitrile CAS 23184-45-4 chemical structure

Description

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.

1H-imidazol-2-ylacetonitrile (CAS 23184-45-4), molecular formula C5H5N3 and molecular weight 107.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, 1H-imidazol-2-ylacetonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 107.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
