Upadacitinib Impurity 95 CAS CATO-C4X-240595

Description

Compared with other compounds in its class, the molecular weight of 389.45 g/mol gives Upadacitinib Impurity 95 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Upadacitinib Impurity 95 (CAS CATO-C4X-240595) is a certified pharmaceutical impurity reference standard with the molecular formula C22H23N5O2 and a molecular weight of 389.45 g/mol.

Based on its molecular formula C22H23N5O2, Upadacitinib Impurity 95 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 389.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 manufactures Upadacitinib Impurity 95 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
