Varenicline Impurity 71 CAS CATO-C4X-196271

Description

Compared with other compounds in its class, the molecular weight of 241.29 g/mol gives Varenicline Impurity 71 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Varenicline Impurity 71 (CAS CATO-C4X-196271), a pharmacopoeial impurity reference standard (molecular formula C14H15N3O, MW 241.29 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Varenicline Impurity 71 (C14H15N3O) 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 its high hydrophobicity (logP), 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 Varenicline Impurity 71 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.
