Description
CATO manufactures Ilaprazole Impurity 105 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 Ilaprazole Impurity 105 (CAS CATO-C4X-1130105), a pharmacopoeial impurity reference standard (molecular formula C15H16N4O3S, MW 332.38 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C15H16N4O3S, Ilaprazole Impurity 105 contains a nitrogen-containing heterocyclic scaffold, 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 332.38 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.
