1-Undecanethiol is widely used in the field of nanotechnology and materials science for the functionalization of nanoparticles, particularly gold nanoparticles. It acts as a stabilizing agent, preventing aggregation and ensuring uniform dispersion in various solutions. This chemical is also employed in self-assembled monolayers (SAMs) on surfaces, which are crucial for modifying surface properties such as wettability, adhesion, and corrosion resistance. In addition, 1-Undecanethiol finds applications in the development of biosensors and electronic devices, where it helps in creating precise and controlled interfaces. Its role in organic synthesis as a building block for more complex molecules further highlights its versatility in chemical research and industrial processes.
