Description

2-[3-(n-Ethylacetylamino)-2,4,6-Triiodophenoxy]Butyric Acid is a high-purity iodinated organic compound primarily used as a key intermediate in pharmaceutical synthesis. Its value lies in its role as a critical building block for the production of advanced X-ray contrast media agents, which are essential for diagnostic imaging. This product is specifically needed by pharmaceutical manufacturers, research institutions, and fine chemical suppliers engaged in the development and production of non-ionic, low-osmolar contrast agents.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of modern, non-ionic iodinated contrast media such as iopromide, iohexol, and ioversol.
• Diagnostic Imaging Agent Synthesis: Used in the manufacturing chain for X-ray and computed tomography (CT) scan contrast agents.
• Research & Development: Serves as a standard or starting material in medicinal chemistry research for novel radiopaque compounds.
• Fine Chemical Production: Employed in custom synthesis and the production of specialized iodinated aromatic compounds for various applications.

Quality Control

Our 2-[3-(n-Ethylacetylamino)-2,4,6-Triiodophenoxy]Butyric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical intermediate use. Certificates of Analysis (COA) documenting purity, related substances, and residual solvents are available upon request, supporting compliance with cGMP and ICH guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
