Quality Control

Our 2,3-o-Cyclohexylidene-L(-)-Erythruronolactone is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
