【禁售不询】Esketamine Impurity N1 CAS 6740-88-1

Description

CATO manufactures 【禁售不询】Esketamine Impurity N1 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.

CATO supplies 【禁售不询】Esketamine Impurity N1 (CAS 6740-88-1), a pharmacopoeial impurity reference standard (molecular formula C13H16ClNO, MW 237.73 g/mol) used for the identification and quantification of trace impurities in APIs.

【禁售不询】Esketamine Impurity N1 (C13H16ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
