Description

2-[[3-(n-Ethylacetylamino)-2,4,6-Triiodophenyl]Oxy]Hexanoic 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 meets stringent safety and efficacy standards. It is essential for manufacturers in the pharmaceutical and diagnostic imaging industries developing non-ionic, low-osmolar contrast agents.

Application

• Pharmaceutical Intermediate: Primary use as a building block in the synthesis of iodinated X-ray contrast agents like iopamidol, iohexol, and ioversol.
• Diagnostic Imaging: Serves as a precursor for non-ionic, low-osmolar contrast media used in computed tomography (CT), angiography, and urography.
• Research & Development: Utilized in academic and industrial R&D for developing new contrast media with improved safety profiles and imaging characteristics.
• Fine Chemical Synthesis: Employed in custom synthesis and process development for complex, high-value iodinated aromatic compounds.
