Diatrizoate Sodium (CAS 737-31-5) Suppliers and Product Information

Diatrizoate sodium is an iodinated radiocontrast agent used in radiology for diagnostic purposes. It functions as an X-ray contrast medium by blocking X-rays, allowing body structures containing iodine to be delineated against those without iodine. It is commonly used in angiography, urography, radiography, and computer tomography (CT) scans.

This compound is also utilized as a density gradient reagent for blood cell separation in laboratory settings.

Frequently Asked Questions

Q: What is the main use of diatrizoate sodium?

A: Diatrizoate sodium is primarily used as an X-ray contrast agent in various diagnostic imaging procedures, including angiography, urography, radiography, and CT scans. It helps visualize veins, the urinary system, gastrointestinal tract, spleen, and joints.

Q: How does diatrizoate sodium work?

A: Diatrizoate sodium works by blocking X-rays. When introduced into the body, it allows structures containing iodine to be clearly delineated against those without iodine, enhancing visibility in X-ray imaging.

Q: Are there any situations where diatrizoate sodium is preferred over other contrast agents?

A: Yes, diatrizoate sodium is often used in cases where barium (another common contrast agent) is not suitable, such as when a patient is allergic to barium.

Q: What are the physical properties of diatrizoate sodium?

A: Diatrizoate sodium is a white or almost white powder with no odor and a slightly salty taste. It dissolves easily in water but only slightly in ethanol, and it's insoluble in ether.
