Used as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its stability and solubility profile make it suitable for reactions with aryl and heteroaryl halides, particularly in pharmaceutical and agrochemical research. The 3-chlorobenzyl group allows for further functionalization or serves as a building block in bioactive molecule development. It is favored in some cases over boronic acids due to reduced protodeboronation and improved handling.
