Chemical Structure

4-Methyl-2,5-diphenyl-1H-imidazole CAS 2654-31-1 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.

4-Methyl-2,5-diphenyl-1H-imidazole (CAS 2654-31-1) is a high-purity analytical reference standard with the molecular formula C16H14N2 and a molecular weight of 234.30 g/mol.

Structurally, 4-Methyl-2,5-diphenyl-1H-imidazole (C16H14N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 234.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 4-Methyl-2,5-diphenyl-1H-imidazole 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.
