Quality Control

Our 3,4,6-Tri-o-Methyl-D-Galactal is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and synthesis. Each lot is characterized by NMR, HPLC, and optical rotation to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is 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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
