1-Decanethiol is widely used in the field of nanotechnology and materials science. It serves as a stabilizing agent for gold nanoparticles, helping to control their size and prevent aggregation. This chemical is also employed in self-assembled monolayers (SAMs) on gold surfaces, which are crucial for creating precise molecular architectures in sensors and electronic devices. Additionally, 1-Decanethiol finds application in surface modification to alter the wettability and adhesion properties of materials, making it valuable in coatings and lubricants. Its role in organic synthesis as a reagent for introducing thiol groups further extends its utility in various chemical processes.
