Used as a coupling reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It enables the formation of carbon-carbon bonds by reacting with aryl or vinyl halides in the presence of a palladium catalyst. The trifluoroborate group enhances stability and solubility, making it easier to handle and store compared to more reactive organoboron compounds. Commonly applied in the synthesis of pharmaceuticals, agrochemicals, and complex organic molecules where selective and efficient coupling is required. Its secondary butyl group allows access to branched alkyl structures, which are useful in building molecular complexity in drug development and materials science.
