α, ω-BIS-[5-(DIHYDROXYALKYL) AMINOCARBONYL-3-HYDROXYACYL-AMINO-2,4,6-TRIIODO-BENZOYL-AMINO]-OXAALKANE COMPOUNDS OF THE FORMULA STR1 wherein R1 is STR2 R and R' are hydrogen or methyl, R2 is dihydroxyalkyl having 3 or 4 carbon atoms, N is 2 or 3, M is an integer between 1 and 5, and N(m+1) is an integer between 4 and 12, Are readily soluble in water to yield injectable radiopaque contrast compositions which are well tolerated and stable. The compounds are prepared in good yields by reacting a reactive derivative of a 5-(di-hydroxyalkyl)aminocarbonyl-3-acyloxyacylamino-2,4,6-triiodo-benzoic acid with an α,ω-diamino-oxaalkane of the formula
