Quality Control

Our production of Bis[2-[Ethyl(Nonafluorobutanesulphonyl)Amino]Ethyl] Hydrogen Phosphate adheres to a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by HPLC, identification by FT-IR and NMR, and impurity profiling to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

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