Chemical Structure

Nintedanib Impurity 167 CAS CATO-C4X-1814167 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nintedanib Impurity 167.

CATO supplies Nintedanib Impurity 167 (CAS CATO-C4X-1814167), a pharmacopoeial impurity reference standard (molecular formula C15H22N4O2, MW 290.36 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Nintedanib Impurity 167 (C15H22N4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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 manufactures Nintedanib Impurity 167 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.
