Used as a molecular building block in the fabrication of self-assembled monolayers (SAMs) on gold surfaces, enabling precise control over surface properties in nanoscale devices. Its thiol groups bind strongly to metals, making it ideal for creating conductive molecular junctions in molecular electronics. Employed in the development of biosensors and electrochemical sensors due to its ability to link functional molecules to electrode surfaces. Also utilized in supramolecular chemistry to construct metal-organic frameworks and other nanostructures with tailored electronic characteristics.
