N4,N4'-Bis(4-bromophenyl)-N4,N4'-di-p-tolyl-[1,1'-biphenyl]-4,4'-diamine CAS 195730-47-3

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'-Bis(4-bromophenyl)-N4,N4'-di-p-tolyl-[1,1'-biphenyl]-4,4'-diamine.

CATO supplies N4,N4'-Bis(4-bromophenyl)-N4,N4'-di-p-tolyl-[1,1'-biphenyl]-4,4'-diamine (CAS 195730-47-3), a certified reference material (molecular formula C38H30Br2N2, MW 674.47 g/mol) for analytical method development and quality control.

The molecular framework of N4,N4'-Bis(4-bromophenyl)-N4,N4'-di-p-tolyl-[1,1'-biphenyl]-4,4'-diamine (C38H30Br2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
