Quality Control

Every batch of L-Erythro-Hexonic Acid, 2,5-Anhydro-3,4-Dideoxy-, Methyl Ester (9Ci) is produced and controlled under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency for your critical research and development projects. A detailed Certificate of Analysis (COA) is supplied with each shipment, typically including results from HPLC, NMR, and optical rotation analysis.

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.
