Quality Control

Our Potassium Benzo[B]Thiophene-2-Yltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 19F, 11B), HPLC for purity assessment, and KF titration for moisture content, to ensure it meets the high standards required for sensitive cross-coupling reactions. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon or nitrogen) for long-term stability and to maintain reactivity. Keep away from incompatible materials such as strong acids and oxidizing agents.
