Quality Control

Our trans-4-Octene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Every lot is analyzed using advanced techniques including Gas Chromatography (GC) and FTIR spectroscopy to confirm identity, purity, and the absence of significant isomers or impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C (refrigerated) to minimize evaporation and maintain stability. Keep away from strong oxidizing agents.
