Quality Control

Our production of Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,10,10,10-Hexadecafluoro-9-(Trifluoromethyl)Decyl Phosphate adheres to a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and assay, 19F/31P/1H NMR for structural confirmation, and Karl Fischer titration for moisture content. We provide full traceability and detailed Certificates of Analysis (COA) with every shipment to ensure consistent performance and compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at a controlled room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen or argon) is recommended for long-term stability to prevent moisture absorption and potential hydrolysis. Keep the container tightly sealed when not in use.
