Quality Control

Our 9,9-Dimethyl-9H-Fluorene-2,7-Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and consistent lot-to-lot performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
