Description

2-[[3-(n-Propylacetylamino)-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. Its molecular structure, featuring a triiodinated aromatic ring, is critical for imparting the radiopacity required in diagnostic imaging agents. This high-purity intermediate is essential for pharmaceutical manufacturers and advanced research facilities developing next-generation non-ionic contrast agents.

Application

• Pharmaceutical Intermediate: Primary building block for the synthesis of non-ionic, low-osmolar X-ray contrast media such as Iopromide and related compounds.
• Diagnostic Imaging Research: Used in R&D for developing novel contrast agents with improved safety profiles and imaging efficacy.
• Active Pharmaceutical Ingredient (API) Synthesis: A critical precursor in the multi-step manufacturing process of final contrast agent APIs.
• Radiology & Medical Diagnostics: Contributes to the production of agents used in computed tomography (CT), angiography, and urography.
• Chemical Reference Standard: Serves as a high-purity standard for analytical method development and quality control in pharmaceutical labs.

Quality Control

Our 2-[[3-(n-Propylacetylamino)-2,4,6-Triiodophenyl]Oxy]Hexanoic Acid is manufactured under strict quality systems to meet the exacting standards of the pharmaceutical industry. Production adheres to current Good Manufacturing Practices (cGMP) where applicable, ensuring traceability and consistency. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We commit to rigorous quality testing to ensure compliance with industry standards and customer-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
