Quality Control

Our .Beta.-D-Galactopyranoside, 4-Hydroxybutyl is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR 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 manufacturing standards.

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 after use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
