Quality Control

Our Methyl 3-o-Benzyl-β-D-Galactopyranoside is manufactured 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 specified 98% minimum purity and is free from critical impurities. A detailed Certificate of Analysis (COA) documenting all test results is provided with each shipment to guarantee traceability and compliance with your research or production standards.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
