Quality Control

Every batch of (5E,7E)-5,7-Dodecadiene is produced and tested under strict quality management protocols to ensure identity, purity, and consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay, stereochemical 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, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
