Used as an 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. The tetrahydropyranyl group acts as a protecting group for alcohols in multistep synthesis, offering stability under various reaction conditions while being removable under mild acidic conditions. Its ether linkage and ring structure contribute to solubility and moderate reactivity, useful in modifying molecular properties during development of active ingredients.
