Tetrabutylammonium tetrahydroborate (Cat No.: I041513) is a quaternary ammonium salt containing a tetrahydroborate (BH₄⁻) anion, known for its strong reducing properties. It serves as a soluble and efficient hydride donor in organic synthesis, particularly in aprotic solvents. This reagent is useful for the selective reduction of aldehydes, ketones, and imines under mild conditions. Its lipophilic tetrabutylammonium cation enhances solubility in organic media, making it advantageous in phase-transfer catalysis and non-aqueous reduction reactions. Proper handling is required due to its reactive nature.
