Ozanimod Impurity 32 (CAS CATO-C4X-290232) is a certified pharmaceutical impurity reference standard with the molecular formula C14H18N2OS and a molecular weight of 262.37 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Ozanimod Impurity 32 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.37 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.
As a certified reference material (CRM), Ozanimod Impurity 32 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.
