Chemical Structure

9,10-Bis[N-(m-tolyl)anilino]anthracene CAS 189263-81-8 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.

CATO supplies 9,10-Bis[N-(m-tolyl)anilino]anthracene (CAS 189263-81-8), a certified reference material (molecular formula C40H32N2, MW 540.70 g/mol) for analytical method development and quality control.

The molecular framework of 9,10-Bis[N-(m-tolyl)anilino]anthracene (C40H32N2) 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), 9,10-Bis[N-(m-tolyl)anilino]anthracene 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.
