Description:1-Dodecanethiol, with the CAS number 112-55-0, is a straight-chain aliphatic thiol characterized by a twelve-carbon alkyl chain terminated by a thiol (-SH) functional group. It is a colorless to pale yellow liquid at room temperature, exhibiting a distinct sulfurous odor. This compound is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic alkyl chain. 1-Dodecanethiol is known for its ability to form self-assembled monolayers on metal surfaces, making it valuable in surface chemistry and nanotechnology applications. It is also used as a reagent in organic synthesis and as a stabilizing agent in the preparation of nanoparticles. The compound is relatively stable under normal conditions but should be handled with care due to its potential toxicity and irritant properties. Overall, 1-dodecanethiol serves as an important building block in various chemical processes and materials science.
