Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other 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 bioconjugation applications. Also employed in materials science for constructing functional polymers and molecular frameworks with tailored electronic properties.
