Description

2-[3-(n-Ethylacetylamino)-2,4,6-Triiodophenyl]Propionic Acid is a high-purity, iodinated organic compound primarily used as a key intermediate in the synthesis of X-ray contrast media. Its value lies in its precise molecular structure, which is critical for producing safe and effective diagnostic imaging agents. This product is essential for pharmaceutical manufacturers and advanced chemical synthesis facilities developing non-ionic, low-osmolar contrast agents for medical radiology.

Application

• Pharmaceutical Intermediate: Primary building block for synthesizing iopromide, iopamidol, and other non-ionic iodinated contrast media.
• Diagnostic Imaging Agent Synthesis: Core precursor in the production of X-ray and computed tomography (CT) contrast agents.
• Research & Development: Used in academic and industrial R&D for developing new radiopaque compounds and studying structure-activity relationships.
• Fine Chemical Production: Serves as a specialized intermediate in custom synthesis and contract manufacturing for the life sciences sector.
