Quality Control

Our (E)-4-Ethynyl-5-Decene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment 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) at 2-8°C to minimize oxidation and degradation due to its highly volatile and easily oxidized nature. Keep away from heat, sparks, and open flames. For long-term storage, consider freezing at -20°C.
