Description
CATO supplies Rotigotine Impurity 31 (CAS CATO-C4X-192731), a pharmacopoeial impurity reference standard (molecular formula C13H19NO, MW 205.30 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C13H19NO, Rotigotine Impurity 31 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.30 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 Rotigotine Impurity 31 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.
