Used as a key intermediate in the synthesis of functional polymers and specialty materials, particularly in the development of proton-conductive membranes for fuel cells. Its structure enables strong hydrogen bonding and coordination with acidic groups, enhancing ionic conductivity in humid environments. Also employed in the preparation of corrosion inhibitors for metals in aggressive industrial settings. Additionally, it serves as a building block in pharmaceutical research, where its heterocyclic core supports the design of bioactive molecules targeting enzyme regulation and cellular signaling pathways.
