Quality Control

Our o-(4-Hydroxy-3-Iodophenyl)-3-Iodo-L-Tyrosine is produced 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 research and synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry 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, especially after the original container is opened. Keep away from strong oxidizing agents.
