Chemical Structure
Description
Based on its molecular formula C14H17N5HCl, Upadacitinib Impurity 81 2HCl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.78 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).
CATO supplies Upadacitinib Impurity 81 2HCl (CAS CATO-C4X-240581), a pharmacopoeial impurity reference standard (molecular formula C14H17N5HCl, MW 291.78 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
