Quality Control

Our (1R,8S)-Rel-9-Oxabicyclo[6.1.0]Non-4-Ene is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for research and development applications. We provide comprehensive analytical data, including chiral purity verification. Certificates of Analysis (COA) detailing identity, purity (by GC/HPLC), and impurity profiles are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and allowed to reach ambient temperature before opening to minimize moisture ingress and degradation. Keep away from heat, sparks, and open flame.
