Quality Control

Our Dihydroguaiaretic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial and research use. Certificates of Analysis (COA) documenting purity, physical characteristics, and test results are provided and available upon request.

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 sensitivity to oxidation, it is recommended to store the product under an inert atmosphere for long-term preservation. Keep away from heat and incompatible materials.
