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 the 3,4-dimethylphenyl group, enabling the formation of carbon-carbon bonds in pharmaceuticals, agrochemicals, and fine chemicals. Its cyclic structure enhances stability and handling compared to more sensitive boronic acids or esters, making it suitable for multi-step syntheses and industrial applications where reproducibility and safety are important.
