What is 2-Ethyl-1-hexanethiol?
Occurrence
Reported found in potato.
The Uses of 2-Ethyl-1-hexanethiol
2-Ethylhexanethiol can be used as a capping agent on the gold surface for the development of chemiresistive vapor sensors. It also forms a SAM on copper indium sulfide (CuInS2) which can be used as an active layer on organic electronic devices such as organic light emitting diodes (OLEDs) and solar cells.
What are the applications of Application
2-Ethylhexanethiol is used in the study of self-assembled monolayers
Definition
ChEBI: 2-Ethyl-1-hexanethiol is an alkanethiol.
General Description
2-Ethylhexanethiol is an organothiol that forms a self-assembled monolayer (SAM) on a variety of surfaces such as metal oxides and metals. It modifies the surface by acting as a corrosion inhibitor and increases the stability of the surface.
