Used as a boron-containing reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, where it serves as a stable and reactive boronic ester equivalent. Its cyclic structure enhances stability and selectivity, making it suitable for constructing biaryl compounds in pharmaceuticals and agrochemicals. Also employed in the development of boron-based sensors and functional materials due to its predictable reactivity and ease of handling.
