2-Chloroethoxytrimethylsilane
2-Chloroethoxytrimethylsilane (CAS 18157-17-0) is an organosilicon compound with the linear formula ClCH2CH2OSi(CH3)3 and a molecular weight of 152.69 g/mol. It is a valuable intermediate in organic synthesis, particularly in the formation of silicon-containing compounds and as a protecting group. Supplied by Tech Serve Solutions with an assay of 98%, it serves as a versatile reagent in chemical research and development.

Organosilicon Synthesis
2-Chloroethoxytrimethylsilane is employed as a building block for introducing the trimethylsilyloxyethyl moiety into organic molecules. This is useful in the synthesis of more complex organosilicon compounds with tailored properties.
Protecting Group Chemistry
The trimethylsilyl group can act as a protecting group for alcohols. The chloroethoxy functionality provides a handle for further reactions after deprotection or can be involved in subsequent synthetic transformations.
Intermediate in Pharmaceutical Research
As a reactive silane derivative, it can serve as an intermediate in the multi-step synthesis of pharmaceutical candidates or complex organic molecules where precise functionalisation is required.
