Description

Diatrizoic Acid Lysine Salt is a key iodinated organic compound primarily used as an active pharmaceutical ingredient (API) in the formulation of X-ray contrast media. Its high iodine content and favorable solubility profile make it essential for enhancing radiographic imaging of internal organs and vascular structures. This compound is critical for manufacturers in the pharmaceutical and diagnostic imaging industries requiring reliable, high-purity components for injectable solutions.

Application

• X-ray Contrast Media Formulation: Primary active ingredient in ionic, high-osmolality contrast agents for angiography, urography, and computed tomography (CT) scans.
• Diagnostic Imaging Solutions: Used in the preparation of injectable solutions for visualizing the renal tract, blood vessels, and cardiac chambers.
• Pharmaceutical Intermediates: Serves as a critical precursor or salt form in the synthesis of specialized contrast media products.
• Research & Development: Utilized in biochemical and medical research for studying radiopaque agents and their pharmacokinetics.
