Quality Control

Our 1,5-Cyclooctadiene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment and is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) to maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
