Quality Control

Our (2E,4Z)-2,4-Dodecadiene is produced and handled under strict quality management protocols. Each batch is analyzed to ensure high chemical and isomeric purity, with comprehensive testing including identity confirmation by IR spectroscopy and purity assessment by gas chromatography (GC). Certificates of Analysis (COA) detailing all specifications 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, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under inert gas when possible.
