Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals, particularly in the preparation of pyridine-containing compounds. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and bioconjugation. Also employed in materials science for constructing conjugated systems in organic electronics due to its ability to form extended π-networks through coupling reactions.
