Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiarrhythmic drugs. It serves as a building block in the preparation of metal-organic frameworks (MOFs) due to its ability to act as a bridging ligand. Also employed in the manufacture of agrochemicals and specialty polymers, where its aromatic and ester functionalities contribute to molecular stability and reactivity. Its derivatives are explored in coordination chemistry for catalytic applications.
