Tetramethoxysilane is used in corrosion resistant coatings and in catalysts. It is also used in the production of silicone. Further, it is employed in the sol-gel synthesis of chromium-doped silicates and in the formation of hexagonal mesoporous silica layers. In addition, it is used in synthetic chemistry to prepare ketals and acetals from ketones and aldehydes respectively.
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.
