Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of benzimidazoles and related nitrogen-containing rings. Employed in coordination chemistry as a ligand for transition metals, forming stable complexes with catalytic activity. Applied in the development of fluorescent sensors due to its ability to chelate metal ions and exhibit optical responses. Also utilized in organic synthesis for building blocks in pharmaceuticals and agrochemicals. Shows potential in antimicrobial and antifungal agent research due to bioactive derivatives.
