Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its alkyne functionality allows for 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 synthesis of heterocyclic compounds due to its reactive triple bond and amide group, which can be further modified to build complex molecular structures. Its methyl group provides steric and electronic modulation, enhancing selectivity in certain transformations.
