Quality Control

Our D-Arabino-Hex-1-Enitol, 1,2-Dideoxy-5,6-o-(1-Methylethylidene)-, Cyclic Carbonate (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 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.
