What is Phenethyltrichlorosilane?
The Uses of Phenethyltrichlorosilane
Trichloro(phenethyl)silane is a useful reagent for the preparation of fluorinated polyhedral oligomeric silsesquioxanes.
General Description
Trichloro(phenethyl)silane (PTS) is a silane based capping agent that can be used to form a self-assembled monolayer (SAM) on a variety of surfaces. It facilitates the surface treatment and modification for effective detection of surface atoms.
