CH3SiOCH2CH33

CH3SiOCH2CH33, also known as ethyl trimethylsiloxy silane, is an organosilicon compound. Its chemical formula indicates a central silicon atom bonded to three methyl groups (CH3) and one ethoxy group (OCH2CH3). The silicon-oxygen bond is characteristic of siloxane linkages. This compound is typically a colorless liquid at room temperature with a mild odor. It has a relatively low viscosity and is soluble in many organic solvents, but generally insoluble in water.

The reactivity of ethyl trimethylsiloxy silane is primarily influenced by the silicon-oxygen bond and the ethoxy group. The Si-O bond can be cleaved under certain conditions, such as in the presence of acids or bases, leading to the formation of silanol groups. The ethoxy group can also participate in reactions, particularly hydrolysis, where it reacts with water to form ethanol and a silanol. These properties make it useful as an intermediate or building block in the synthesis of other silicon-containing materials. It can be employed in the production of silicone polymers, resins, and coatings. Its ability to modify surfaces and introduce hydrophobic properties is also a notable application.
