Description
CATO supplies Deucravacitinib Impurity 2 (CAS CATO-C4X-31382), a pharmacopoeial impurity reference standard (molecular formula C18H19N7O2, MW 365.39 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Deucravacitinib Impurity 2 (C18H19N7O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 365.39 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
