Quality Control

Our Daphnin is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including identification (IR, HPLC), assay (HPLC), and impurity profiling, to meet the stringent requirements of research and industrial applications. A detailed Certificate of Analysis (COA) documenting purity, physical characteristics, and test results is provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture.
