Quality Control

Our D-Hamamelose is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification by IR and NMR, purity assay by HPLC, and specific tests for residual solvents and moisture, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
