Quality Control

Our (+)-3,4-Dichloro-7,8-Dihydro-2,8,8-Trimethyl-6H-Furo[3,2-H][1]Benzopyran-5,7-Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
