Chemical Structure

N,N'-bis(2-methylphenyl)benzene-1,4-diamine CAS 15017-02-4 chemical structure

Description

N,N'-bis(2-methylphenyl)benzene-1,4-diamine (CAS 15017-02-4), molecular formula C20H20N2 and molecular weight 288.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N,N'-bis(2-methylphenyl)benzene-1,4-diamine (C20H20N2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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'-bis(2-methylphenyl)benzene-1,4-diamine 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.
