Quality Control

Our (S)-4'-Hydroxy-4-Methoxydalbergione is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with every shipment.

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 light-sensitive nature and propensity for oxidation, prolonged exposure to light, heat, or air should be avoided. For long-term storage, consider under an inert atmosphere.
