Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and bioconjugation. The benzyl ether group can act as a protecting group for phenols during multi-step syntheses. It is also employed in the development of functionalized polymers and materials science where controlled molecular architecture is required.
