Chemical Structure

Varenicline Impurity 40 CAS CATO-C4X-196240 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 281.35 g/mol gives Varenicline Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Varenicline Impurity 40 (CAS CATO-C4X-196240), a pharmacopoeial impurity reference standard (molecular formula C17H19N3O, MW 281.35 g/mol) used for the identification and quantification of trace impurities in APIs.

Varenicline Impurity 40 (C17H19N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 40 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.
