Description
As a certified reference material (CRM), Ponatinib Impurity 39 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 Ponatinib Impurity 39 (CAS 2702457-83-6), a pharmacopoeial impurity reference standard (molecular formula C6H4BrN3, MW 198.02 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C6H4BrN3, Ponatinib Impurity 39 contains a nitrile group, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
