Chemical Structure

Upadacitinib Impurity 68 CAS CATO-C4X-240568 chemical structure

Description

Upadacitinib Impurity 68 (C6H6N4) contains a nitrile group, an aromatic ring system. Its physicochemical properties are representative of its class; 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).

As a process- or degradation-related impurity, Upadacitinib Impurity 68 (CAS CATO-C4X-240568, C6H6N4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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), Upadacitinib Impurity 68 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.
