Used primarily in medical diagnostics, this compound serves as a contrast agent in radiographic imaging. It helps enhance the visibility of internal structures during X-ray examinations, particularly in the gastrointestinal tract. Its iodine content makes it effective for absorbing X-rays, providing clearer images for accurate diagnosis of conditions like blockages, tumors, or abnormalities. Additionally, it is sometimes employed in research settings to study iodine uptake and metabolism in biological systems. Proper handling is essential due to its potential toxicity and sensitivity to light.
