Abstract
Novel non-ionic contrast media are provided, which fulfill the requirements for x-ray visualization media, while being biodegradable. The compounds are characterized by being triiodo-3,5-diaminobenzoic acid derivatives, where the functional groups are derivatized with hydroxyalkyl groups and the amino functionalities are further derivatized with acyl substituents of one carbon acids. Also, triiodophloroglucinol oxyalkyl substituted derivatives are provided.
