Description

3-[7-[[3-Carboxy-2,4,6-Triiodo-5-(Propylcarbamoyl)Phenyl]Carbamoyl]Heptanoylamino]-2,4,6-Triiodo-5-(Propylcarbamoyl)Benzoic Acid is a high-purity, iodinated organic compound designed for advanced pharmaceutical and diagnostic applications. This compound is critical for its role as a key intermediate in the synthesis of modern X-ray contrast media agents, which are essential for high-resolution medical imaging. It is primarily required by manufacturers in the pharmaceutical and medical diagnostics industries for the production of non-ionic, low-osmolar contrast agents.

Application

• Pharmaceutical Intermediate: Primary use as a critical building block in the synthesis of non-ionic iodinated X-ray contrast media.
• Diagnostic Imaging Agent Synthesis: Used in the manufacture of contrast agents for computed tomography (CT), angiography, and urography.
• Research & Development: Serves as a reference standard and starting material in R&D for novel diagnostic compounds and improved imaging formulations.
• Chemical Synthesis: Utilized in organic synthesis for creating complex, triiodobenzene-based molecular structures.
• Quality Control: Employed as an analytical standard in QC laboratories to ensure the purity and consistency of final contrast agent products.
