Quality Control

Our Trans,trans-2,8-Decadiene is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and spectroscopic methods, to ensure identity, purity, and isomer specificity. Certificates of Analysis (COA) detailing all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature: 2-8°C.
