Description
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.
Pitavastatin Impurity 41 (CAS CATO-C4X-103741) is a certified pharmaceutical impurity reference standard with the molecular formula C19H16BrN and a molecular weight of 338.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, Pitavastatin Impurity 41 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Pitavastatin Impurity 41 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.
