Quality Control

Our Vinylcyclooctane is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR) spectroscopy, to verify identity and assay. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to support your quality assurance and regulatory compliance 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 area at room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged exposure to air should be avoided. Keep away from heat, sparks, and open flames.
