Chemical Structure
Description
Vonoprazan Fumarate Impurity 90 (CAS CATO-C4X-102090) is a certified pharmaceutical impurity reference standard with the molecular formula C33H27F3N4HCl and a molecular weight of 573.06 g/mol.
The molecular framework of Vonoprazan Fumarate Impurity 90 (C33H27F3N4HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
