Description
CATO supplies Iloperidone Impurity 9 (CAS CATO-C4X-16619), a pharmacopoeial impurity reference standard (molecular formula C24H27FN2O5, MW 442.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C24H27FN2O5, Iloperidone Impurity 9 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 442.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), Iloperidone Impurity 9 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
