Ziprasidone Impurity 80 CAS CATO-C4X-124080

Description

Compared with other compounds in its class, the molecular weight of 271.76 g/mol gives Ziprasidone Impurity 80 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ziprasidone Impurity 80 (CAS CATO-C4X-124080) is a certified pharmaceutical impurity reference standard with the molecular formula C11H13N3OSHCl and a molecular weight of 271.76 g/mol.

Ziprasidone Impurity 80 (C11H13N3OSHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
