Quality Control

Our (E,E)-Undeca-1,3,5-Triene is produced and handled under strict quality management protocols. Each batch is analyzed to ensure high chemical purity and isomeric integrity, with comprehensive testing including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, 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 extended stability.
