It can be used as a diagnostic aid agent during angiography, urography and radiography. It can be applied during visualizing veins, the urinary system, gastrointestinal tract, spleen and joints as well as during the computer tomography (CT scan). It is used in cases where barium is not suitable for application such as patient being allergic to barium. The mechanism of action of Diatrizoate sodium is that it can block the X-rays so that the body structure containing iodine to be delineated in contrast to those structures that free of iodine, further allowing the visualization of those related areas.

Definition ChEBI: The sodium salt of a benzoic acid having iodo substituents at the 2-, 4- and 6-positions and acetamido substituents at the 3- and 5-positions. It is used, often as a mixture with the meglumine salt, as an X-ray contrast medium in gastrointestinal studies, ngiography, and urography. Manufacturing Process 3,5-Dinitrobenzoic acid (15.9 g) was dissolved in an equivalent amount of sodium hydroxide solution, and the solution was diluted to 310 ml with water. The solution was refluxed with Raney nickel for fifteen minutes, filtered, and the filtrate was hydrogenated at elevated pressure using platinum oxide catalyst. After the amount of hydrogen calculated to reduce both nitro groups had been absorbed, the mixture was filtered, and the filtrate was acidified with an equal volume of concentrated hydrochloric acid. Iodine monochloride (17 ml) in 100 ml of 6N HCl was then added with stirring. The reaction mixture was allowed to stand for two and one-half hours at room temperature, then diluted with an equal amount of water with vigorous stirring, and the solid material was collected by filtration and recrystallized from dilute methanol, giving 18.5 g of 3,5-diamino-2,4,6-triiodobenzoic acid, MP about 135°C with decomposition. The 18.5 g of 3,5-diamino-2,4,6- triiodobenzoic acid was suspended in 150 ml of acetic anhydride containing 5 drops of 70% perchloric acid, and the mixture was heated on a steam bath for three and one-half hours. The reaction mixture was poured into 300 ml of ice water, and then heated on a steam bath until crystallization took place. The solid material was collected by filtration, dissolvedin dilute sodium hydroxide solution, filtered, and hydrochloric acid was added to the filtrate to reprecipitate the acid product. The latter was again dissolved in sodium hydroxide and reprecipitated with acid, giving 9 g of 3,5-diacetamido-2,4,6- triiodobenzoic acid, MP above 250°C. The acid may be used as the sodium salt or as the meglumate. Brand name Md (Mallinckrodt); Urovist Sodium (Berlex).
