Quality Control

Our (E)-3-Octen-5-Yne is produced and handled under strict quality management protocols. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

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 must be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
