Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antitumor and antimicrobial agents. It serves as a building block in organic reactions where the bromine atom allows for further functionalization through cross-coupling reactions such as Suzuki or Heck reactions. Commonly employed in the preparation of biologically active compounds, including kinase inhibitors and receptor antagonists. Also utilized in the manufacture of agrochemicals and dyes due to its stable heterocyclic structure.
