Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Heck reactions, to construct biaryl and styrene derivatives. Its bromine atom acts as a good leaving group, enabling palladium-catalyzed transformations in pharmaceutical and agrochemical development. The isopropanesulfonyl group provides electron-withdrawing character, enhancing reactivity and influencing regioselectivity in subsequent reactions. Commonly employed in the preparation of functionalized aromatic compounds for materials science and medicinal chemistry.
