Quality Control

Our Methyl 6-o-Tosyl-β-D-Galactopyranoside is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and specific tests for residual solvents and moisture. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 should be kept in a desiccated environment. For long-term storage, consider storing under an inert atmosphere.
