Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. Its alkyne functionality allows for use in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient conjugation in drug discovery and development. The bromo group provides a site for further functionalization via cross-coupling reactions like Suzuki or Sonogashira couplings. It is also employed in the synthesis of kinase inhibitors and other targeted therapeutic agents. Its structural features make it valuable in building complex aromatic and conjugated systems for materials science and medicinal chemistry applications.
