Quality Control

Our Trans,trans-2,4-Hexadiene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical and isomeric purity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production specifications.

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, away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and handled with appropriate precautions to minimize exposure to air and moisture. Recommended long-term storage temperature is 2-8°C.
