Quality Control

Our 1,3-Octadiene is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request and are integral to our commitment to supply chain transparency and reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
