Compared with other compounds in its class, the molecular weight of 267.19 g/mol gives Irinotecan Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Irinotecan Impurity 15 (CAS 143254-82-4), a pharmacopoeial impurity reference standard (molecular formula C11H19ClN2OHCl, MW 267.19 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C11H19ClN2OHCl, Irinotecan Impurity 15 contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 267.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Irinotecan Impurity 15 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.
