Used primarily as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. It serves as a boronic ester equivalent of 3-chlorophenyl, allowing for the introduction of the 3-chlorophenyl group into aromatic systems under palladium catalysis. This makes it valuable in the preparation of pharmaceutical intermediates, agrochemicals, and functional materials where substituted biaryl structures are needed. Its stability and reactivity profile make it suitable for use in both laboratory-scale and industrial applications involving transition metal-catalyzed transformations.
