Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its alkyne and hydroxyl functional groups allow for versatile reactivity, including click chemistry via copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and bioconjugation. Also employed in the development of functional materials and heterocyclic compounds due to its ability to undergo cyclization and coupling reactions.
