Quality Control

Our D-Ribonic Acid, 2,3-Anhydro-2-C-Carboxy-5-Deoxy-, 1,4-Lactone (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

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. For long-term storage, consider using desiccants.
