Quality Control

Our Potassium (3-Fluoro-4-Biphenyl)Trifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and consistent performance in sensitive coupling reactions. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment.

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., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from incompatible materials.
