Safety Information
1-Dodecanethiol Usage And Synthesis
  • Uses1-Dodecanethiol can be used as a chain transfer agent in the polymerization of methyl methacrylate.
    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.
    1-Dodecanethiol can also be used for development of the 1-dodecanethiol-based phase transfer protocol for the highly efficient extraction of noble metal ions from aqueous phase.
  • Contact Toxicity1-Dodecanethiol can cause severe skin burns and eye damage. It may cause an allergic skin reaction. It is very toxic to aquatic life with long lasting effects.
  • Chemical Propertiesclear liquid
  • UsesDodecyl mercaptan is a poymerization inhibitor added to polyurethane resins and Neoprene glues for use, e.g., in the shoe industry.
  • General DescriptionOily colorless liquid with a mild skunk odor. Freezing point 19°F.
  • Air & Water ReactionsAir and moisture sensitive. Insoluble in water. Reacts vigorously with water or steam.
  • Reactivity Profile1-Dodecanethiol is incompatible with bases, oxidizing agents, reducing agents and alkali metals. Easily oxidized to disulfide.
  • Health HazardLiquid is irritating to skin, eyes, and mucous membranes. Ingestion may cause nausea. Repeated skin exposure can cause dermatitis and may produce a sensitizing effect.
  • Fire HazardSpecial Hazards of Combustion Products: Poisonous and irritating gases (e.g., sulfur dioxide) are generated in fires.
  • Purification MethodsDry it with CaO for several days, then distil it from CaO. [Beilstein 1 IV 1851.]
