Quality Control

Our Trans,Trans,trans-1,5,9-Cyclododecatriene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and HPLC analysis, to ensure high chemical purity and isomeric consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

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. Due to its highly volatile and easily oxidized nature, prolonged exposure to air, heat, or light should be avoided. Recommended storage temperature is 2-8°C for long-term stability.
