As a certified reference material (CRM), 1-((4-Ethylphenyl)amino)-3-methylbenzo[4,5]imidazo[1,2-a]pyridine-4-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 1-((4-Ethylphenyl)amino)-3-methylbenzo[4,5]imidazo[1,2-a]pyridine-4-carbonitrile (CAS 336178-06-4), a certified reference material (molecular formula C21H18N4, MW 326.39 g/mol) for analytical method development and quality control.

Structurally, 1-((4-Ethylphenyl)amino)-3-methylbenzo[4,5]imidazo[1,2-a]pyridine-4-carbonitrile (C21H18N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 326.39 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
