Used as a key intermediate in organic synthesis, particularly in the preparation of complex natural products and pharmaceuticals. 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. The tetrahydropyranyl group serves as a protective moiety for alcohols, enabling selective reactions in multi-step syntheses. It is also employed in the development of functional materials and agrochemicals due to its stability and reactivity profile.
