Quality Control

Every batch of 4,5-Dihydroxy-9H-fluoren-9-one is manufactured under strict quality management systems. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment. Specifications can be tailored to meet specific project requirements, including custom purity grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
