Quality Control

Our 2,5-3,4-Dianhydroaltritol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling by HPLC, to ensure it meets the high standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment and is available 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 moisture absorption, which may affect product stability and performance.
