General description

Dimethyldichlorosilane(DMDCS) is a tetrahedral organosilicon compound. It is used as a silane coupling agent to synthesis the hydrophilic and hydrophobic silica nanoparticles. It is also used in the synthesis of polysilanes, which are precursors to silicon carbide.

Application
