Used as a key intermediate in the synthesis of nylon-6,6, where it serves to introduce sulfur functionality for enhanced polymer cross-linking and thermal stability. Employed in surface modification of gold nanoparticles and self-assembled monolayers (SAMs) due to the strong gold-sulfur interaction, enabling applications in biosensors and molecular electronics. Acts as a coupling agent in organic synthesis, facilitating the attachment of biomolecules to solid supports in diagnostic assays. Also utilized in the development of corrosion inhibitors and lubricant additives, where the thiol group provides strong adsorption on metal surfaces.
