Chemical Structure

m-Phenylenediamine Impurity 3 CAS CATO-C4X-34283 chemical structure

Description

The molecular framework of m-Phenylenediamine Impurity 3 (C14H14N2) 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).

CATO supplies m-Phenylenediamine Impurity 3 (CAS CATO-C4X-34283), a pharmacopoeial impurity reference standard (molecular formula C14H14N2, MW 210.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), m-Phenylenediamine Impurity 3 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.
