Quality Control

Our (2R,3S)-3,4-Dihydro-2-[4-Hydroxy-3-(3-Methyl-2-Butenyl)Phenyl]-2H-1-Benzopyran-3,7-Diol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral HPLC for enantiomeric purity, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) providing identity, purity, and impurity profile is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and stored in a dark environment to maintain stability and purity. For long-term storage, consider using desiccants and an inert atmosphere.
