N,N'-Bis[4-di(m-tolyl)aminophenyl]-N,N'-diphenylbenzidine CAS 199121-98-7

Description

The occurrence of N,N'-Bis[4-di(m-tolyl)aminophenyl]-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-di(m-tolyl)aminophenyl]-N,N'-diphenylbenzidine (CAS 199121-98-7) is a high-purity analytical reference standard with the molecular formula C64H54N4 and a molecular weight of 879.14 g/mol.

Structurally, N,N'-Bis[4-di(m-tolyl)aminophenyl]-N,N'-diphenylbenzidine (C64H54N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 40.0, corresponding to approximately 40 ring(s) or double-bond equivalent(s). With a molecular weight of 879.14 g/mol, it falls into the high-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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
