Quality Control

Our 2,4-Octadiene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including purity assay and identity confirmation. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

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 container tightly sealed when not in use.
