Used as a key intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of bioactive molecules and natural product analogs. Its alkyne functionality allows for use in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient molecular assembly in drug discovery and materials science. Also employed in the preparation of conjugated organic materials for optoelectronic applications due to its ability to extend π-systems in molecular frameworks.
