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.
4,4'-(Diphenylmethylene)bis(N,N-diphenylaniline) (CAS 1459723-98-8) is a high-purity analytical reference standard with the molecular formula C49H38N2 and a molecular weight of 654.84 g/mol.
The molecular framework of 4,4'-(Diphenylmethylene)bis(N,N-diphenylaniline) (C49H38N2) 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.
As a certified reference material (CRM), 4,4'-(Diphenylmethylene)bis(N,N-diphenylaniline) 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.
