Quality Control

Our production of 4-[3,5-Bis(1,1-Dimethylethyl)-4-Hydroxyphenoxy]-3,5-Diiodobenzenepropanoic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) detailing all test results are provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the original container has been opened.
