Description
Potassium Butyltrifluoroborate (CAS No. 444343-55-9) is a highly specialized organoboron compound with the molecular formula C4H9BF3K. This reagent is widely utilized in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, due to its stability and reactivity under mild conditions. The compound features a butyl group attached to a trifluoroborate anion, balanced by a potassium counterion, ensuring excellent solubility in polar solvents such as water and alcohols. With a purity of ≥95%, it is an essential tool for researchers and scientists working in pharmaceuticals, agrochemicals, and materials science. Each batch is rigorously tested via NMR, HPLC, and elemental analysis to guarantee consistency and performance.
Available in convenient packaging options (1g, 5g, 10g, 25g), this product is stored under inert conditions to maintain stability. Its moisture-sensitive nature requires handling under anhydrous environments. Synonyms include Potassium butyl(trifluoro)borate(1-) and MFCD08276805, as listed in major chemical databases (e.g., PubChem, Reaxys).
