Quality Control

Our Cyclooctadecane-1,3,5,7,9,11,13,15,17-Nonene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic and spectroscopic methods, to verify identity and assay. Certificates of Analysis (COA) documenting purity and specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
