Used as a corrosion inhibitor in acidic environments, particularly for protecting mild steel in industrial cleaning and pickling processes. It forms a protective layer on metal surfaces by adsorbing through its nitrogen and oxygen donor atoms, reducing metal degradation and hydrogen embrittlement. Also investigated for its potential in sensing applications due to its ability to undergo structural changes upon protonation or metal ion binding. Shows moderate activity in biological studies, including antimicrobial and antioxidant properties, making it a candidate for further development in medicinal chemistry.
