Quality Control

Our 1,2-Cyclononadiene is produced and handled under strict quality protocols to ensure batch-to-batch consistency and purity for research and development applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, GC-MS, NMR) to confirm identity and assess purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures between 2°C and 8°C. Keep the container in a cool, well-ventilated place, away from heat, sparks, and open flame.
