Used as a crosslinking agent in polymer chemistry, particularly in the synthesis of conductive and conjugated polymers. Its dual thiol groups enable strong binding to metal surfaces and nanoparticles, making it valuable in nanotechnology for assembling molecular junctions and modifying electrode surfaces. Commonly employed in self-assembled monolayers (SAMs) to create structured interfaces in sensors and electronic devices. Also utilized in the preparation of metal-organic frameworks (MOFs) and as a linker in supramolecular chemistry due to its flexible alkyl chain and reactive end groups.
