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 naphthalen-2-yl groups, enabling the formation of biaryl compounds which are important in pharmaceuticals, agrochemicals, and materials science. Its cyclic dioxaborinane structure enhances stability and handling compared to more sensitive boronic acids or esters, making it valuable in multi-step syntheses and industrial applications where reproducibility and safety are critical.
