Chemical Structure

Iomeprol Impurity 4 CAS 2068038-50-4 chemical structure

Description

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 Iomeprol Impurity 4 (CAS 2068038-50-4), a pharmacopoeial impurity reference standard (molecular formula C17H22I3N3O8, MW 777.09 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H22I3N3O8, Iomeprol Impurity 4 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 777.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
