Quality Control

Our Ammonium Tetrafluorosuccinate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and impurity profiling by HPLC, to ensure it meets the high-purity standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and under an inert atmosphere such as nitrogen or argon for long-term storage to prevent degradation.
