As a certified reference material (CRM), Palonosetron Impurity 17 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.
Palonosetron Impurity 17 (CAS CATO-C4X-110517) is a certified pharmaceutical impurity reference standard with the molecular formula C19H24BCl2N2OCl and a molecular weight of 413.57 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Palonosetron Impurity 17 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 413.57 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.
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.
