This compound is primarily utilized in organic synthesis as a versatile intermediate for the development of complex molecules. Its structure, featuring a bromine atom and a benzoxepinone ring, makes it a valuable building block in pharmaceutical research, particularly for the synthesis of biologically active compounds. It is often employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce the benzoxepinone moiety into target molecules. Additionally, its reactivity allows for further functionalization, enabling the creation of diverse chemical libraries for drug discovery. Researchers also explore its potential in the development of novel therapeutic agents, including central nervous system (CNS) drugs, due to its unique structural features.
