Quality Control

Every batch of 7-Ethenyl-5-Undecene is produced and tested under a stringent quality management system to ensure consistency and reliability for industrial applications. Our standard grade typically meets a purity specification of ≥95% (GC), with detailed impurity profiling available. A comprehensive Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as identity, assay, and specific impurities.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this product should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to minimize volatility and degradation. Keep away from heat, sparks, open flames, and oxidizing agents.
