Description
General description
1-Dodecanethiol (DDT) is an alkyl thiol that forms a self-assembled monolayer (SAM) and can be used as an organic source of sulfur with balanced physio-chemical properties.

Application
DDT can be used as a source of sulfur for the synthesis CdS quantum dots (QDs) and lead sulfide nanoparticles (PbS) which find potential applications in energy efficient lighting, solar cells and as ammonium gas sensing agents.
It may be used to form a self-assembled monolayer (SAM) on copper surface as a corrosion resistant coating.
Functionalization with DDT may form SAMs on geranium (Ge) to improve the surface characteristics for futuristic applications in microelectronics.

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.

Lauryl mercaptan is an oily colorless liquid with a mild skunk odor. Freezing point 19°F.

Influence of n-dodecyl mercaptan as chain transfer agent in dispersion polymerization of styrene  [2008]
Lee, Ki-Chang; Wi, Han-Ah;
Dispersion polymerization of styrene with n-dodecyl mercaptans (DDM) as the chain transfer agent was investigated.
PS particles with various molecular weight, molecular weight distribution (MWD), and particle diameter were prepared by varying the concentration of DDM and also the addition time of DDM before and after the particle nucleation. The average particle diameter was increased, whereas polymerization rate, molecular weight, and MWD were decreased with increasing DDM concentrations from 0 to 10 wt %. The effect of addition of DDM before and after particle nucleation was studied at 0.4, 0.8, and 1.0 wt % DDM. The addition of DDM before particle nucleation produced PS particles of relatively large particle diameter and low molecular weight when compared with the addition of DDM after particle nucleation. This study shows that particle nucleation occurs in about 5-6 min, which corresponds to the 15-16% conversion, 372-378 nm in Dn, and provides a facile way to control the particle size and interesting information about the particle formation using the delayed addition of DDM.
