Used as a corrosion inhibitor in acidic environments, particularly in industrial cleaning and metal processing. It protects metals like steel by forming a protective layer on the surface, reducing acid attack. Also investigated for its potential in sensing applications due to its ability to interact with metal ions. Shows moderate biological activity, with studies exploring its use in antimicrobial and enzyme inhibition contexts. Its structure allows for hydrogen bonding and metal coordination, making it useful in designing selective receptors or extractants in separation processes.
