Quality Control

Our 5,6-Undecadiene is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and spectroscopic methods, 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. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at 2-8°C or as specified on the label. Keep away from heat, sparks, and open flames. Containers must be kept tightly sealed when not in use to prevent evaporation and potential degradation.
