Quality Control

Our (R)-5-Butyl-3,4-Dihydro-6,8-Dihydroxy-3-[(E)-3-Pentenyl]-1H-2-Benzopyran-1-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chiral purity verification, to meet the exacting standards required for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
