Quality Control

Our 3,4-Dihydro-6-Hydroxy-2,2,7,8-Tetramethyl-2H-1-Benzopyran-5-Methanol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
