Quality Control

Our production of n-Ethylheptadecafluoro-n-[2-(Phosphonooxy)Ethyl]Octanesulphonamide adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and titration methods, to ensure consistent purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from strong bases and oxidizing agents.
