Quality Control

Our 1,2-Distearoyldigalactosylglyceride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and MS for identity verification, to ensure it meets the stringent requirements for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) for long-term stability. This product is hygroscopic (moisture-sensitive) and easily oxidized. Allow the sealed container to reach room temperature before opening to prevent condensation. For short-term use, store desiccated at 2-8°C.
