Quality Control

Our 2-[3-(n-Ethylpropionylamino)-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 high standards required for pharmaceutical intermediate applications. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and residual solvents is provided with every shipment.

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 product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat and incompatible materials.
