Quality Control

Our L-Glycero-L-Galacto-Heptitol derivative is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral integrity, NMR for structural confirmation, and KF for moisture content, to ensure it meets the high standards required for research and pharmaceutical development. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider inert atmosphere conditions.
