Chemical Structure

m-Phenylenediamine Impurity 5 CAS CATO-C4X-34285 chemical structure

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO supplies m-Phenylenediamine Impurity 5 (CAS CATO-C4X-34285), a pharmacopoeial impurity reference standard (molecular formula C12H14N4, MW 214.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, m-Phenylenediamine Impurity 5 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 214.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures m-Phenylenediamine Impurity 5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
