Ozanimod Impurity 17 CAS 58161-38-9 chemical structure

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.

CATO supplies Ozanimod Impurity 17 (CAS 58161-38-9), a pharmacopoeial impurity reference standard (molecular formula C11H13NO, MW 175.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ozanimod Impurity 17 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 175.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Ozanimod 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.
