N4,N4'-di-m-tolyl-[1,1'-biphenyl]-4,4'-diamine CAS 78888-06-9

Description

The occurrence of N4,N4'-di-m-tolyl-[1,1'-biphenyl]-4,4'-diamine 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.

N4,N4'-di-m-tolyl-[1,1'-biphenyl]-4,4'-diamine (CAS 78888-06-9) is a high-purity analytical reference standard with the molecular formula C26H24N2 and a molecular weight of 364.48 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N4,N4'-di-m-tolyl-[1,1'-biphenyl]-4,4'-diamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
