Applications
(3-Mercaptopropyl)trimethoxysilane is used as a capping molecule for cadmium sulphide nanocrystals. It is used in the preparation of multi-walled carbon nanotubes and bilayer modified gold electrode. It acts as a linker molecule used in the preparation of gold multilayers and as a molecular adhesive in the fabrication of vapor-deposited gold electrodes on glass substrates. It is also used as a precursor for silica.

Solubility
Miscible with methanol, ethanol, isopropanol, acetone, benzene, toluene and xylene.

Notes
Air and moisture sensitive. Incompatible with strong oxidizing agents, strong acids, alcohols and water. Decomposes in water.
