Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure allows for selective modifications at the bromo position, enabling the development of receptor ligands and enzyme inhibitors. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce aromatic or heteroaromatic groups. Valuable in medicinal chemistry for constructing dihydroisoquinoline-based scaffolds found in neuroprotective and antipsychotic agents. Also utilized in the preparation of fluorescent probes and imaging agents due to its stable ring system and derivatization potential.
