N4,N4-Diphenyl-[1,1'-biphenyl]-4,4'-diamine CAS 84161-87-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N4,N4-Diphenyl-[1,1'-biphenyl]-4,4'-diamine.

CATO supplies N4,N4-Diphenyl-[1,1'-biphenyl]-4,4'-diamine (CAS 84161-87-5), a certified reference material (molecular formula C24H20N2, MW 336.43 g/mol) for analytical method development and quality control.

Based on its molecular formula C24H20N2, N4,N4-Diphenyl-[1,1'-biphenyl]-4,4'-diamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
