Description

n-(4-(((Carboxymethyl)Amino)Carbonyl)-2,3,5,6-Tetraiodobenzoyl)-n-(Phenylmethyl)Glycine is a specialized iodinated organic compound primarily used as a key intermediate in the synthesis of X-ray contrast media. Its high iodine content and specific molecular architecture are critical for developing non-ionic, low-osmolar contrast agents that offer improved patient safety and diagnostic clarity. This high-purity intermediate is essential for pharmaceutical manufacturers and advanced research facilities focused on diagnostic imaging and radiopharmaceutical development.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of non-ionic X-ray contrast agents like iopamidol and iohexol.
• Diagnostic Imaging Agent Synthesis: Used in research and production of advanced contrast media for computed tomography (CT) and angiography.
• Radiopharmaceutical Research: Serves as a precursor in the development of novel iodine-containing compounds for medical imaging.
• Chemical Reference Standard: Employed as a high-purity standard for analytical method development and quality control in pharmaceutical manufacturing.
• Organic Synthesis Building Block: Utilized in specialized organic reactions where a heavily iodinated, functionalized benzene core is required.
