.alpha., .omega.-BIS-[5-(DIHYDROXYALKYL) AMINOCARBONYL-3-HYDROXYACYL-AMINO-2,4,6-TRIIODO-BENZOYL-AMINO]-OXAALKANE COMPOUNDS OF THE FORMULA ##STR1## wherein R.sub.1 is ##STR2## R and R' are hydrogen or methyl, R.sub.2 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 .alpha.,.omega.-diamino-oxaalkane of the formula R--NH--C.sub.n H.sub.2n --(O--C.sub.n H.sub.2n)--NH--R.
α,ω-双[5-(二羟基烷基)氨基甲酰-3-羟基酰胺-2,4,6-三碘苯甲酰氨基]-氧烷类化合物的化学式为##STR1##其中R.sub.1为##STR2##R和R'为氢或甲基,R.sub.2为具有3或4个碳原子的二羟基烷基,N为2或3,M为1到5之间的整数,N(m+1)为4到12之间的整数,可溶于水中,形成可注射的放射性造影剂,耐受性好且稳定。这些化合物通过将5-(二羟基烷基)氨基甲酰-3-酰氧基酰胺-2,4,6-三碘苯甲酸的活性衍生物与α,ω-二氨基氧烷类化合物反应而制备得到,其中α,ω-二氨基氧烷的化学式为R--NH--C.sub.n H.sub.2n --(O--C.sub.n H.sub.2n)--NH--R。
