Used as a corrosion inhibitor in acidic environments, particularly in industrial cleaning and pickling processes. It protects metal surfaces such as steel and copper by forming a protective film that prevents acid attack. Also shows potential as a ligand in coordination chemistry for designing metal ion sensors due to its ability to chelate transition metals. Exhibits biological activity in some studies, suggesting possible use in pharmaceutical research, particularly in anti-inflammatory or antimicrobial applications. Its structure allows for hydrogen bonding and π-π interactions, making it useful in supramolecular chemistry and crystal engineering.
