Quality Control

Our production of 5-Cyclooctene-1,2-Diol, 3-Methylene-, (1R,2S)-Rel- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and development applications. All materials are characterized using advanced analytical techniques including NMR, HPLC, and GC. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and identity is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
