Quality Control

Our 2,3-o-Isopropylidene-1,6-Ditosyl-L-Sorbose is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the exacting standards required for advanced synthetic applications. Certificates of Analysis (COA) with full traceability are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. Keep away from incompatible materials.
