Quality Control

Our 3,4-Dihydroxy-9H-Fluoren-9-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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 exposure to air and moisture.
