Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 409.40 g/mol gives Deucravacitinib Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Deucravacitinib Impurity 13 (CAS 2245111-18-4), a pharmacopoeial impurity reference standard (molecular formula C19H19N7O4, MW 409.40 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Deucravacitinib Impurity 13 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.40 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).
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), Deucravacitinib Impurity 13 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.
