Deucravacitinib Impurity 3 CAS CATO-C4X-31383

Description

The occurrence of Deucravacitinib Impurity 3 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Deucravacitinib Impurity 3 (CAS CATO-C4X-31383), a pharmacopoeial impurity reference standard (molecular formula C38H38N16O6, MW 814.81 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, Deucravacitinib Impurity 3 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 814.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 3 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.
