Quality Control

Every batch of (5E,7Z)-5,7-Dodecadiene is produced and tested under a strict quality management system. Our products undergo rigorous analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and isomer specification compliance. Certificates of Analysis (COA) documenting all critical parameters are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and only opened in a controlled environment. Recommended storage temperature: 2-8°C for long-term stability.
