Used as a boron-based reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling. It serves as a stable source of the 2-chlorophenyl group, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical intermediates. Its cyclic borinate structure enhances stability and handling compared to more sensitive boronic acids or esters, making it suitable for use in air- and moisture-sensitive transformations. Commonly applied in the preparation of biaryl compounds and functionalized aromatic systems in research and development settings.
