What is Iopromide?

Plain description, key identifiers and synonyms

Iopromide is a dicarboxylic acid diamide that consists of N-methylisophthalamide bearing three iodo substituents at positions 2, 4 and 6, a methoxyacetyl substituent at position 5 and two 2,3-dihydroxypropyl groups attached to the amide nitrogens. A water soluble x-ray contrast agent for intravascular administration. It has a role as a xenobiotic, a radioopaque medium, a nephrotoxic agent and an environmental contaminant. It is a dicarboxylic acid diamide and an organoiodine compound. It is functionally related to a glycerol and an isophthalamide.
