(E)-4,4'-(Ethene-1,2-diyl)bis(N,N-diphenylaniline) CAS 202748-68-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4,4'-(Ethene-1,2-diyl)bis(N,N-diphenylaniline).

(E)-4,4'-(Ethene-1,2-diyl)bis(N,N-diphenylaniline) (CAS 202748-68-3) is a high-purity analytical reference standard with the molecular formula C38H30N2 and a molecular weight of 514.66 g/mol.

The molecular framework of (E)-4,4'-(Ethene-1,2-diyl)bis(N,N-diphenylaniline) (C38H30N2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), (E)-4,4'-(Ethene-1,2-diyl)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.
