Chemical Structure
Description
4-(2-Methylimidazol-1-yl)-2,2-diphenylbutanenitrile (CAS 214777-43-2), molecular formula C20H19N3 and molecular weight 301.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(2-Methylimidazol-1-yl)-2,2-diphenylbutanenitrile (C20H19N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 301.38 g/mol, it falls into the moderately-high-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.
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-(2-Methylimidazol-1-yl)-2,2-diphenylbutanenitrile 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.
