Netupitant Impurity 26 CAS CATO-C4X-122326 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 Netupitant Impurity 26 (CAS CATO-C4X-122326), a pharmacopoeial impurity reference standard (molecular formula C12H10F6O3, MW 316.20 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C12H10F6O3, Netupitant Impurity 26 contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 316.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

CATO manufactures Netupitant Impurity 26 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.
