Used in organic synthesis as a chiral building block for pharmaceuticals and fine chemicals. Its terminal alkyne group allows participation in click chemistry reactions, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient coupling with azides to form triazoles. The hydroxyl group can be further functionalized, making it useful in the development of complex molecules with stereochemical control. Commonly applied in the synthesis of bioactive compounds and natural product analogs.
