Useful:

• Canonical SMILES: CCO[Si](C)(C)C
• Uses: Ethoxytrimethylsilane is also called Trimethylethoxysilane, an intermediate useful for blocking hydroxyl or amino groups to perform reactions on multi-functional organic compounds or polymers. It is also useful for deactivating glass surfaces used in gas chromatographic applications. Ethoxytrimethylsilane is used in preparation method of solvent-free heavy peeling regulator for silicon release.

Technology Process of Ethoxytrimethylsilane

There total 123 articles about Ethoxytrimethylsilane which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use.
