Description

2-[[3-(n-Ethylpropanoylamino)-2,4,6-Triiodophenyl]Oxy]Hexanoic Acid is a specialized iodinated organic compound with a high molecular weight, primarily valued for its role as a key intermediate in the synthesis of advanced X-ray contrast media. Its complex structure, featuring a triiodinated aromatic ring, is engineered to provide the necessary radiopacity and pharmacokinetic properties required for diagnostic imaging agents. This high-purity intermediate is essential for manufacturers in the pharmaceutical industry developing non-ionic, low-osmolar contrast agents for enhanced patient safety and diagnostic clarity.

Application

• Pharmaceutical Intermediate: Primary use as a critical building block in the synthesis of non-ionic X-ray contrast media (e.g., Iopromide, Ioversol analogs).
• Diagnostic Imaging Agent Synthesis: Key precursor for manufacturing iodinated compounds used in computed tomography (CT), angiography, and urography.
• Research & Development: Used in academic and industrial R&D for developing new generations of contrast agents with improved safety profiles.
• Fine Chemical Production: Serves as a high-value intermediate in custom synthesis and contract manufacturing for the life sciences sector.
