Chemical Structure
Description
The occurrence of 5'-(4-Cyanophenyl)-2',4',6'-trimethyl-[1,1':3',1''-terphenyl]-4,4''-dicarbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5'-(4-Cyanophenyl)-2',4',6'-trimethyl-[1,1':3',1''-terphenyl]-4,4''-dicarbonitrile (CAS 2278192-35-9), molecular formula C30H21N3 and molecular weight 423.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5'-(4-Cyanophenyl)-2',4',6'-trimethyl-[1,1':3',1''-terphenyl]-4,4''-dicarbonitrile (C30H21N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 5'-(4-Cyanophenyl)-2',4',6'-trimethyl-[1,1':3',1''-terphenyl]-4,4''-dicarbonitrile 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.
