Used in organic synthesis, particularly in the development of pharmaceuticals and bioactive compounds. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for constructing complex molecular architectures. Commonly employed in the synthesis of indole-based drug candidates, including those targeting neurological disorders and cancer. Also utilized in materials science for creating conjugated systems and fluorescent probes due to its aromatic and electronic properties.
