Quality Control

Our 5,6,7,8-Tetrahydro-3-Methoxy-8,8-Dimethyl-1,4-Phenanthrenedione is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
