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.
CATO supplies Vonoprazan Impurity 169 (CAS CATO-C4X-1020169), a pharmacopoeial impurity reference standard (molecular formula C32H25F3N4HCl, MW 559.03 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Vonoprazan Impurity 169 (C32H25F3N4HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 559.03 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
