Quality Control

Our Nonafluorobutanesulphonicacidhydrate95% is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including assay (by titration or HPLC), water content (KF titration), and impurity profiling, to ensure it meets the specified 95% minimum purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance with your technical requirements.

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). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; ensure containers are kept tightly sealed to exclude moisture and are compatible with acidic substances. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
