Quality Control

Our Bicyclo[3.2.0]Heptane-2,7-Diol, 2,5-Dimethyl-, (1R,2R,5R,7S)-Rel- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure high chemical and isomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed specifications are provided to guarantee batch-to-batch consistency and traceability.

Storage

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