Quality Control

Our 1,2-Cyclooctadiene is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 area. Recommended storage temperature is 2-8°C to minimize polymerization and oxidation. Keep away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, containers should be kept sealed and only opened in a controlled environment.
