Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.48 g/mol gives Amorolfine Impurity 83 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Amorolfine Impurity 83 (CAS CATO-C4X-154283), a pharmacopoeial impurity reference standard (molecular formula C20H33NO2, MW 319.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Amorolfine Impurity 83 (C20H33NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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 Amorolfine Impurity 83 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.
