Chemical Structure

N4,N4-Di([1,1'-biphenyl]-4-yl)-N4'-phenyl-[1,1'-biphenyl]-4,4'-diamine CAS 858127-33-0 chemical structure

Description

As a certified reference material (CRM), N4,N4-Di([1,1'-biphenyl]-4-yl)-N4'-phenyl-[1,1'-biphenyl]-4,4'-diamine 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.

N4,N4-Di([1,1'-biphenyl]-4-yl)-N4'-phenyl-[1,1'-biphenyl]-4,4'-diamine (CAS 858127-33-0) is a high-purity analytical reference standard with the molecular formula C42H32N2 and a molecular weight of 564.72 g/mol.

The molecular framework of N4,N4-Di([1,1'-biphenyl]-4-yl)-N4'-phenyl-[1,1'-biphenyl]-4,4'-diamine (C42H32N2) 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. 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.
