Used as a corrosion inhibitor in acidic environments, particularly in industrial cleaning and pickling processes. It forms a protective layer on metal surfaces, reducing the rate of metal dissolution. Also exhibits potential as a sensor compound due to its ability to chelate with metal ions, showing color changes useful in analytical detection. Shows moderate biological activity, being studied for antimicrobial and antioxidant applications in pharmaceutical research. Its structure allows for hydrogen bonding and π-π interactions, making it a candidate in supramolecular chemistry for designing functional materials.
