Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 780.52 g/mol gives Iopamidol Impurity 56 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Iopamidol Impurity 56 (CAS CATO-C4X-145056), a pharmacopoeial impurity reference standard (molecular formula C17H20ClI3N2O7, MW 780.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C17H20ClI3N2O7, Iopamidol Impurity 56 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 780.52 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.
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.
