N,N'-Diphenyl-N,N'-di(p-tolyl)benzidine CAS 20441-06-9

Description

Compared with other compounds in its class, the molecular weight of 516.67 g/mol gives N,N'-Diphenyl-N,N'-di(p-tolyl)benzidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N,N'-Diphenyl-N,N'-di(p-tolyl)benzidine (CAS 20441-06-9) is a high-purity analytical reference standard with the molecular formula C38H32N2 and a molecular weight of 516.67 g/mol.

The molecular framework of N,N'-Diphenyl-N,N'-di(p-tolyl)benzidine (C38H32N2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

As a certified reference material (CRM), N,N'-Diphenyl-N,N'-di(p-tolyl)benzidine 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.
