Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical industries. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for constructing complex molecules. Commonly employed in the development of liquid crystals and functional materials due to its rigid aromatic core and reactive ester group. Also utilized in the preparation of UV-absorbing compounds and photoresponsive polymers.
