Description
CATO manufactures Nafamostat Impurity 13 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 Nafamostat Impurity 13 (CAS CATO-C4X-133213), a pharmacopoeial impurity reference standard (molecular formula C26H22N6O3CH4O3S, MW 562.60 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C26H22N6O3CH4O3S, Nafamostat Impurity 13 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 562.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
