PUMECITINIB Impurity 3 CAS CATO-C4X-35663 chemical structure

Description

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.

PUMECITINIB Impurity 3 (CAS CATO-C4X-35663) is a certified pharmaceutical impurity reference standard with the molecular formula C47H33N5 and a molecular weight of 667.80 g/mol.

PUMECITINIB Impurity 3 (C47H33N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

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.
