Used as a key building block in organic synthesis, particularly in pharmaceutical and agrochemical industries. Its alkyne functionality enables click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery for constructing complex molecules. The aromatic ester group allows for further derivatization, including hydrolysis and cross-coupling reactions. Commonly employed in the development of liquid crystals and functional materials due to its rigid benzoate core and reactive ethynyl group. Also utilized in polymer chemistry to introduce aromatic and alkyne moieties into macromolecules for enhanced thermal and mechanical properties.
