Quality Control

Our Cyclononene is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to ensure identity, purity, and consistency. We provide full traceability and a Certificate of Analysis (COA) with every shipment, detailing all critical specifications. Our quality systems are designed to support cGMP and ISO standards for research and industrial applications.

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 place. Recommended long-term storage temperature is 2-8°C. Keep away from heat, sparks, and open flames. The container must be kept tightly closed and upright to prevent leakage and minimize oxidation.
