Chemical Structure

Upadacitinib Impurity 146 CAS CATO-C4X-2405146 chemical structure

Description

Upadacitinib Impurity 146 (C8H14BrNOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Upadacitinib Impurity 146 (CAS CATO-C4X-2405146) is a certified pharmaceutical impurity reference standard with the molecular formula C8H14BrNOHCl and a molecular weight of 256.57 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
