Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of pharmaceuticals and functionalized aromatic derivatives. Its bromoethyl group acts as an alkylating agent, enabling the introduction of the methanesulfonylbenzene moiety into various target molecules. It is also employed in the development of sulfone-containing compounds with potential biological activity. Due to the reactivity of the carbon-bromine bond, it facilitates nucleophilic substitution reactions, making it valuable in the construction of complex organic structures.
