Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals, particularly in the construction of nitrogen-containing heterocycles. 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 the development of nicotinic receptor ligands due to the pyridyl moiety, which mimics natural neurotransmitters. Serves as a building block in materials science for creating functionalized polymers and sensors.
