Quality Control

Our Broussonin B is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and spectroscopic methods (NMR, MS) for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

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 dry environment to prevent degradation.
