Quality Control

Our 1,2-Cycloheptanediol, 1-Methyl-3-Methylene-, (1R,2S)-Rel- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and chiral integrity, meeting the exacting standards required for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, enantiomeric excess, and impurity profile.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat and incompatible materials.
