Summary for Patent: 4,954,348
Title: Non-ionic polyol contrast media from ionic contrast media
Abstract:Novel non-ionic contrast media of a hitherto unknown combination of low osmolality and low viscosity are efficiently prepared from generally available ionic contrast media or non-iodinated precursors. Particularly, polyhydroxyhalo-hydrocarbons are employed with a triiodo-substituted acylamido benzoic acids in aqueous weakly basic media to selectively substitute the amido nitrogen, followed by activation of the carboxyl group for amide formation.
