General description

Triethylene glycol mono-11-mercaptoundecyl ether is an alkanethiol that forms a self-assembled monolayer (SAM) on a variety of surfaces.


Triethylene glycol mono-11-mercaptoundecyl ether can be used in the formation of low cost micro-patterns for biomedical and microelectronics based applications. It can also be used as a SAM for surface immobilization of various molecular species on gold electrodes for biological applications.
Used in an efficient synthesis of ω-functionalized asymmetric disulfides via the sulfenyl bromide.

Various types of asymmetric disulfides can be synthesized under mild conditions and in excellent yields by a method involving dialkoxylthiophosphoranesulfenyl halide precursors. This straightforward, rapid procedure is used to prepare a series of disulfides bearing neutral, acidic, and basic terminal
