Quality Control

Our 5,5,6,6,7,7,8,8,9,9,9-Undecafluorononane-2,4-Dione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance as a synthesis intermediate. A comprehensive Certificate of Analysis (COA) detailing purity, identity, 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. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its reactivity as a strong acid/organic solvent, appropriate secondary containment is recommended. For long-term storage, maintain at controlled room temperature (15-25°C).
