Pirfenidone Impurity 38 CAS CATO-C4X-222938 chemical structure

Description

Pirfenidone Impurity 38 (CAS CATO-C4X-222938) is a certified pharmaceutical impurity reference standard with the molecular formula C6H8N2O and a molecular weight of 124.14 g/mol.

The molecular framework of Pirfenidone Impurity 38 (C6H8N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Pirfenidone Impurity 38 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.
