Description
Ioversol Impurity 10 (CAS CATO-C4X-209110) is a certified pharmaceutical impurity reference standard with the molecular formula C20H28I3N3O10 and a molecular weight of 851.16 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, Ioversol Impurity 10 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 851.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
