Quality Control

Our Sodiumtetrakis(Pentafluorophenyl)Borate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and compliance with your research or production requirements.

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 under an inert atmosphere (e.g., argon or nitrogen) to prevent moisture absorption and decomposition.
