Used as an intermediate in the synthesis of heterocyclic compounds, particularly in the development of pharmaceuticals and agrochemicals. Its functional groups—amino and thiol—allow for selective reactions, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of dyes and functionalized polymers due to its ability to participate in coupling reactions and form metal complexes. Also finds use in material science for surface modification of nanoparticles and sensors, where the thiol group enables strong binding to metal surfaces.
