Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of heterocyclic compounds, particularly in the development of bioactive molecules with potential antimicrobial or anti-inflammatory properties. Also employed in coordination chemistry as a ligand for metal ions, facilitating the formation of metal-organic frameworks (MOFs) and catalysts. Its aromatic and acidic characteristics make it suitable for use in sensor technologies and functional materials.
