Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Acts as a building block in the production of antimalarial, antibacterial, and antioxidant agents. Employed in research for developing novel heterocyclic compounds with potential biological activity. Also utilized in the preparation of dyes and fluorescent probes due to its aromatic structure and ability to form metal complexes. Additionally, serves as a reagent for the analysis of heavy metals in environmental samples, as it forms colored complexes with certain metal ions that can be detected by spectroscopy.
