Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block in the preparation of bioactive molecules due to its reactive bromo group and stable cyclic ether structure. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to construct complex organic frameworks. Also utilized in the research of receptor ligands and functionalized isobenzofuran derivatives for potential therapeutic applications.
