Quality Control

Our production of 1,1,2,2,3,3,4,4,4-Nonafluoro-Butane-1-Sulfonic Acid 2,2,2-Trifluoro-1-Trifluoromethyl-Ethyl Ester adheres to stringent internal quality protocols. Each batch is characterized using advanced analytical techniques including NMR (¹H, ¹⁹F, ¹³C), HPLC, and GC-MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment.

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 sensitivity to strong bases and potential hydrolysis, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to exclude moisture and maintain product integrity.
