Used as an analytical reagent for the detection and separation of certain metal ions due to its ability to form stable complexes. It serves as a key intermediate in the synthesis of heterocyclic compounds, particularly in the development of pharmaceuticals with potential antithyroid and antimicrobial activities. Also employed in the preparation of chelating agents for use in hydrometallurgy and environmental remediation to remove heavy metals from aqueous solutions. Its structural properties make it valuable in research for designing sensors and molecular recognition systems.
