化学的特性

Diatrizoate sodium is a white or almost white powder that has no odor and a slightly salty taste. It dissolves easily in water but only slightly dissolves in ethanol, and it does not dissolve in ether. A 50% aqueous solution has a pH between 6.5 and 8.0. The substance has an iodine content of approximately 59.9%.

使用

Diatrizoate Sodium is an iodinated radiopaque X-ray contrast medium used in radiology for diagnostic purposes. It is also used as a density gradient reagent to separate blood cells.

定義

ChEBI: Sodium amidotrizoate is 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, angiography, and urography. It has a role as a radioopaque medium. It is an organoiodine compound and an organic sodium salt. It contains an amidotrizoic acid anion.

Mode of action

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.
