The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing two linked iodinated phenyl groups of the general formula wherein each R
1
independently are the same or different and denotes a hydrogen atom or a C
1
to C
4
straight of branched alkyl group; each R
2
independently are the same or different and denotes a hydrogen atom or a C
1
to C
4
straight of branched alkyl group; and each R
3
, R
4
and R
5
independently are the same or different and denote C
1
to C
6
straight of branched alkyl moieties substituted by 1 to 6 —OH groups. The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging, and to contrast media containing such compounds.
