Dispersions, émulsions, microémulsions, gels et compositions à usage biomédical comprenant un composé organique fluoré iodé, utilisables notamment comme agent de contraste.

摘要

The present invention relates to nonterminally iodinated fluorinated compositions. The compositions, including, dispersions, emulsions, microemulsions, and gels are useful for biomedical applications, particularly radiography and scintigraphy. The compounds used in the invention preferably have the following general formula:RFCH=CIR1wherein, RF is a linear, branched, or cyclic first fluorocarbon radical, having 2 to 12 carbon atoms in which 50 to 100% of the hydrogen atoms have been replaced by fluorine atoms; and R1 is selected from the group consisting of a second fluorocarbon radical and a hydrocarbon radical, wherein, the second fluorocarbon radical is linear, branched, or cyclic, having 2 to 12 carbon atoms in which 50 to 100% of the hydrogen atoms have been replaced by fluorine atoms; and the hydrocarbon radical is linear, branched, or cyclic, having 2 to 14 carbon atoms.
