Chemical Structure

N1,N1-diphenylbenzene-1,3-diamine CAS 116724-06-2 chemical structure

Description

Structurally, N1,N1-diphenylbenzene-1,3-diamine (C18H16N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 260.33 g/mol, it falls into the medium-molecular-weight range. 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).

CATO supplies N1,N1-diphenylbenzene-1,3-diamine (CAS 116724-06-2), a certified reference material (molecular formula C18H16N2, MW 260.33 g/mol) for analytical method development and quality control.

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.
