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.
