1-Octanethiol is widely used as a surface modifier in the production of nanomaterials, particularly in the synthesis of gold and silver nanoparticles. It forms self-assembled monolayers (SAMs) on metal surfaces, enhancing stability and preventing aggregation. This chemical is also employed in the creation of hydrophobic coatings for various materials, improving their water-repellent properties. In the field of electronics, it serves as a capping agent to control the size and shape of nanoparticles, which is crucial for optimizing their optical and electrical properties. Additionally, 1-octanethiol finds applications in organic synthesis as a reagent for introducing thiol groups into molecules, facilitating further chemical modifications. Its ability to act as a ligand in coordination chemistry makes it valuable in catalysis and material science research.
