4-(4,5-Diphenyl-1H-imidazol-2-yl)benzonitrile CAS 29898-72-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4,5-Diphenyl-1H-imidazol-2-yl)benzonitrile.

4-(4,5-Diphenyl-1H-imidazol-2-yl)benzonitrile (CAS 29898-72-4), molecular formula C22H15N3 and molecular weight 321.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-(4,5-Diphenyl-1H-imidazol-2-yl)benzonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 4-(4,5-Diphenyl-1H-imidazol-2-yl)benzonitrile 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.
