Product Application of 1-Dodecanethiol CAS#112-55-0
1-Dodecanethiol can be used for the synthesis of thiol-stabilized metal nanoparticles (NPs), such as gold nanoparticles and silver nanoparticles, which have been produced for use as catalysts, electronic devices, fillers, sensors and active components in composite materials, and other applications.
This molecule is used for the production of hydrophobic SAMs. It can also be used in mixed SAMs to give a hydrophobic background and act as a spacer to move other functional groups or domains farther apart.
Further, it is utilized as a polymerization inhibitor in polyurethane and neoprene adhesives, which finds application in the footwear industry. In addition to this, it acts as a protein regenerating agent used for the regeneration of native proteins from mercuribenzoate.
