Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral, anticancer, and antimicrobial agents. Its thiol group enables conjugation reactions useful in drug design and facilitates binding to heavy metals for applications in environmental sensors. Also employed in the preparation of heterocyclic compounds, fluorescent and luminescent materials, and coordination chemistry as a ligand for metal ions. Shows potential in material science for modifying surfaces due to its strong binding affinity to metals.
