Iopamidol Impurity 48 (C11H10ClI3N2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Iopamidol Impurity 48 (CAS CATO-C4X-145048) is a certified pharmaceutical impurity reference standard with the molecular formula C11H10ClI3N2O4 and a molecular weight of 650.37 g/mol.
