Quality Control

Our 3,7-Difluoro-2-Nitro-9H-Fluorene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and scale-up. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature, the container should be kept in secondary packaging or amber glass. Keep away from strong oxidizing agents and incompatible materials.
