Key Applications
Self-assembled monolayers on gold and metal surfaces – Widely used to form dense, ordered SAMs that functionalize electrodes, sensors and nanostructures for electronics and biosensing applications.
Crosslinking agent in polymer and elastomer synthesis – Serves as a bifunctional thiol in thiol-ene click chemistry and poly(disulfide) formation to create crosslinked networks and degradable materials.
Chemical intermediate in organic synthesis – Provides a flexible dithiol linker for the preparation of sulfur-containing compounds, ligands and functionalized molecules.
Flavor and fragrance component – Employed at low levels (FEMA 3495) to contribute meaty, burnt-fatty notes in food flavor formulations.
Surface modification of nanomaterials – Applied to functionalize quantum dots, transition-metal dichalcogenides and other nanostructures for optoelectronic and sensing devices.
