Description
As a certified reference material (CRM), Decitabine Impurity 45 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.
CATO supplies Decitabine Impurity 45 (CAS CATO-C4X-113745), a pharmacopoeial impurity reference standard (molecular formula C29H22O3, MW 418.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C29H22O3, Decitabine Impurity 45 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 418.48 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.
