Description

CAS: 4420-74-0 | C6H16O3SSi | 196.336 g/mol

(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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
