Quality Control

Our Trans,Cis,cis-1,5,9-Cyclododecatriene is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) and other relevant methods, to ensure high purity and consistent isomer composition. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature: 2-8°C (refrigerated) or as specified on the label.
