Quality Control

Every batch of (E)-5,6-Diethenylcyclooctene is produced and tested under strict quality management protocols to ensure consistency and purity for research applications. Our standard grade typically meets a purity specification of ≥95% (by GC or HPLC), with rigorous identity confirmation via spectroscopic methods. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profile is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C. This compound is easily oxidized and should be handled in a controlled environment to prevent degradation. Allow the container to reach ambient temperature before opening to minimize moisture ingress.
