Compared with other compounds in its class, the molecular weight of 217.24 g/mol gives Pitavastatin Impurity 83 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pitavastatin Impurity 83 (CAS CATO-C4X-103783), a pharmacopoeial impurity reference standard (molecular formula C13H12FNO, MW 217.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C13H12FNO, Pitavastatin Impurity 83 contains a nitrogen-containing heterocyclic scaffold, 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 217.24 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.
As a certified reference material (CRM), Pitavastatin Impurity 83 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.
