Description
As a certified reference material (CRM), Ozanimod Impurity 28 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.
CATO supplies Ozanimod Impurity 28 (CAS CATO-C4X-290228), a pharmacopoeial impurity reference standard (molecular formula C34H46N4O5Si, MW 618.84 g/mol) used for the identification and quantification of trace impurities in APIs.
Ozanimod Impurity 28 (C34H46N4O5Si) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
