Description

Diatrizoic Acid CAS NO 117-96-4 is a high-purity, iodinated organic compound primarily used as a key active pharmaceutical ingredient (API) in the formulation of X-ray contrast media. Its critical function is to enhance the visibility of internal body structures during diagnostic imaging procedures, enabling accurate medical diagnosis. This compound is essential for manufacturers in the pharmaceutical and diagnostic imaging industries requiring reliable, high-quality raw materials for injectable solutions.

Application

• X-ray Contrast Media: Primary active ingredient in ionic, iodinated contrast agents for radiographic procedures.
• Angiography: Used in formulations for visualizing blood vessels and the heart.
• Urography: Key component in contrast media for imaging the urinary tract, including kidneys and bladder.
• Computed Tomography (CT Scans): Employed in contrast solutions to improve image clarity and diagnostic accuracy in CT imaging.
• Pharmaceutical Intermediates: Serves as a critical building block in the synthesis of more complex contrast agent formulations.
• Diagnostic Reagent Manufacturing: Used by specialty chemical suppliers formulating diagnostic kits and reagents for medical imaging.
