Quality Control

Our 3-(β-D-Galactopyranosyloxy)-5-Hydroxy-2-(4-Hydroxyphenyl)-6,7-Dimethoxy-4H-1-Benzopyran-4-One is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods (IR, NMR) and purity determination by HPLC, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided for traceability and compliance.

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 in a low-humidity environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
