Quality Control

Our Trans cis-1 9-Cyclohexadecadiene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and isomeric consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet 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, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress. Keep away from heat, sparks, and open flames.
