Description
CATO supplies Iloperidone Impurity 5 (CAS 19417-90-4), a pharmacopoeial impurity reference standard (molecular formula C21H24O6, MW 372.41 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C21H24O6, Iloperidone Impurity 5 contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 372.41 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 Iloperidone Impurity 5 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.
