The solubilities of 5-amino-N,N'-bis(2,3-dihydroxypropyl)-2,4,6-triiodobenzene-1,3-dicarboxamide in ethanol + water mixtures at temperatures from (318.15 to 353.15) K were measured. The experimental data were correlated with the Apelblat model. The calculated values of Apelblat model were found to show a fine representation of the experimental data.
