Description

5-Cyano-2,4,6-Triiodoisophthalic Acid is a high-purity, tri-iodinated aromatic compound that serves as a critical intermediate in advanced organic synthesis. Its value lies in its unique molecular structure, which provides multiple reactive sites for constructing complex, iodine-containing molecules essential for specialized applications. This product is primarily needed by manufacturers in the pharmaceutical and diagnostic imaging industries, as well as by research institutions developing novel contrast agents and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key building block for synthesizing X-ray and CT (Computed Tomography) contrast media agents.
• Diagnostic Imaging: Precursor in the production of non-ionic, low-osmolar contrast compounds for enhanced patient safety.
• Chemical Research: Used in academic and industrial R&D for developing new iodinated aromatic derivatives and studying structure-activity relationships.
• Specialty Chemical Synthesis: Intermediate for creating functional dyes, ligands for catalysis, and other high-value, performance chemicals.
