Quality Control

Every batch of D-Glucitol, 2,3:5,6-Dianhydro- (9Ci) is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as identity, purity, and impurity profile. Our quality commitment supports compliance with cGMP and ISO guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the container must be kept in a cool, dry place with minimal humidity fluctuation. Recommended storage temperature is 2-8°C for long-term stability. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
