Quality Control

Our Potassium (Mix)-2-Buten-2-Yltrifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, essential for sensitive cross-coupling reactions. Each lot is analyzed via NMR (¹H, ¹¹B, ¹³C), HPLC, and KF titration to confirm identity, isomeric ratio, purity, and moisture content. 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 material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) when possible to maintain stability and prevent decomposition. Keep away from strong acids and strong bases.
