N4,N4'-dibutyl-[1,1'-biphenyl]-4,4'-diamine CAS 5324-31-2

Description

Compared with other compounds in its class, the molecular weight of 296.45 g/mol gives N4,N4'-dibutyl-[1,1'-biphenyl]-4,4'-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N4,N4'-dibutyl-[1,1'-biphenyl]-4,4'-diamine (CAS 5324-31-2) is a high-purity analytical reference standard with the molecular formula C20H28N2 and a molecular weight of 296.45 g/mol.

The molecular framework of N4,N4'-dibutyl-[1,1'-biphenyl]-4,4'-diamine (C20H28N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
