Quality Control

Our 3,5-Undecadien-2-One is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed 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. 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 storage temperature is 2-8°C for long-term stability.
