Used primarily in organic synthesis as a building block for cross-coupling reactions, especially in Suzuki-Miyaura coupling, enabling the formation of carbon-carbon bonds. Its structure allows for the introduction of functionalized phenyl groups into complex molecules, making it valuable in pharmaceutical and agrochemical research. The bromoethyl group can undergo further transformations, such as cyclization or nucleophilic substitution, facilitating the synthesis of heterocyclic compounds and functionalized aromatic systems. Commonly employed in the development of bioactive molecules and conjugated materials.
