Description

3-[[n-(3-Ethoxy-2,4,6-Triiodophenyl)-n-Ethylamino]Carbonyl]Propionic Acid is a specialized iodinated organic compound primarily used as a key intermediate in the synthesis of X-ray contrast media. This high-purity intermediate is critical for ensuring the final pharmaceutical product's safety, efficacy, and regulatory compliance. It is essential for manufacturers in the pharmaceutical and diagnostic imaging industries developing non-ionic, low-osmolar contrast agents.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of modern, non-ionic X-ray contrast agents like iopromide and ioversol.
• Diagnostic Imaging: Contributes to the production of contrast media used in computed tomography (CT), angiography, and urography.
• Research & Development: Serves as a reference standard and starting material in medicinal chemistry research for novel iodinated compounds.
• Fine Chemical Synthesis: Used in advanced organic synthesis to introduce the triiodophenyl moiety into complex molecules.
