Chemical Structure

3,3'-Bis[di(p-tolyl)amino]biphenyl CAS 161485-60-5 chemical structure

Description

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.

3,3'-Bis[di(p-tolyl)amino]biphenyl (CAS 161485-60-5), molecular formula C40H36N2 and molecular weight 544.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,3'-Bis[di(p-tolyl)amino]biphenyl (C40H36N2) 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).

As a certified reference material (CRM), 3,3'-Bis[di(p-tolyl)amino]biphenyl 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.
