CH3CH2OSiH3

(CH3CH2)OSiH3, also known as ethoxysilane or ethylsilane, is an organosilicon compound. It has the chemical formula C2H7OSi. The molecule consists of an ethyl group (CH3CH2-) attached to an oxygen atom, which is in turn bonded to a silicon atom that is bonded to three hydrogen atoms (SiH3-). This structure can be viewed as a derivative of silane where one hydrogen atom has been replaced by an ethoxy group.

Ethoxysilane is a colorless liquid at room temperature. Its physical properties, such as boiling point and density, are influenced by the presence of both the ethyl and silane functionalities. It is a relatively reactive compound due to the Si-H bonds, which can participate in various chemical reactions, including hydrosilylation and oxidation. The Si-O bond is also a point of reactivity. Due to its reactivity, ethoxysilane is often handled under inert atmosphere conditions to prevent degradation from moisture or oxygen.

In terms of applications, ethoxysilane can serve as a precursor in the synthesis of other silicon-containing materials. Its reactive nature allows for its incorporation into polymers or its use in surface modification. It may also find use in specialized chemical synthesis where a source of ethoxy and silyl groups is required. Research into its properties and potential uses is ongoing within the field of organosilicon chemistry.
