N,N'-Bis[4-(diphenylamino)phenyl]-N,N'-diphenylbenzidine CAS 209980-53-0

Description

The occurrence of N,N'-Bis[4-(diphenylamino)phenyl]-N,N'-diphenylbenzidine 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.

N,N'-Bis[4-(diphenylamino)phenyl]-N,N'-diphenylbenzidine (CAS 209980-53-0) is a high-purity analytical reference standard with the molecular formula C60H46N4 and a molecular weight of 823.03 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N,N'-Bis[4-(diphenylamino)phenyl]-N,N'-diphenylbenzidine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 823.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), N,N'-Bis[4-(diphenylamino)phenyl]-N,N'-diphenylbenzidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
