Aplicaciones

Iodotrimethylsilane is used for the introduction of trimethylsilyl group in organic synthesis. It is also useful for gas chromatography analysis by converting alcohol into a silyl ether derivative, thereby making it more volatile than the original molecule.

Notas

Moisture and light Sensitive. Incompatible withstrong acids, strong bases, strong oxidizing agents and reacts violently with water.
