Used as a boron-based reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling. It serves as a stable and selective source of boronic acid equivalents after hydrolysis, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical intermediates. Its cyclic structure enhances shelf stability and reduces protodeboronation side reactions compared to traditional boronic acids. Commonly applied in late-stage functionalization of complex molecules due to mild reaction conditions and good functional group tolerance.
