Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves in the development of receptor antagonists and enzyme inhibitors due to its reactive bromo functional group and fused ring structure. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex molecules for drug discovery. Also utilized in the preparation of heterocyclic compounds with potential applications in central nervous system agents and anti-inflammatory drugs. Its structural features make it valuable in medicinal chemistry for optimizing lead compounds.
