Quality Control

Our 3,5-Diiodo-Dl-Thyronine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, related substances, and residual solvents.

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 handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
