Used as a reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, where it acts as a source of the tert-butyl group. Its stability and reactivity make it suitable for introducing the tert-butyl moiety into complex molecules, especially in pharmaceutical and agrochemical synthesis. As a boronic ester, it serves as an intermediate in the formation of carbon-carbon bonds. Its bulky structure can influence selectivity in reactions, making it valuable in fine chemical manufacturing.
