Description
CATO supplies Amorolfine Impurity 74 (CAS CATO-C4X-154274), a pharmacopoeial impurity reference standard (molecular formula C21H35NO2, MW 333.51 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Amorolfine Impurity 74 (C21H35NO2) is characterized by a steroid core, 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 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 74 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.
