Description
CATO supplies Carbocisteine Impurity 46 (CAS CATO-C4X-201046), a pharmacopoeial impurity reference standard (molecular formula C8H8O3, MW 152.15 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C8H8O3, Carbocisteine Impurity 46 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 152.15 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.
CATO manufactures Carbocisteine Impurity 46 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.
