Quality Control

Our 5,7-Dodecadiyne is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Every lot is analyzed to confirm the 99% minimum purity and the presence of the specified BHT stabilizer. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided and available upon request to support your quality management systems.

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 flame. Recommended long-term storage temperature is 2-8°C.
