FormLiquid
2-(Trimethylsilyl)ethanol is used as a protecting reagent for carboxyl, phosphoryl, hydroxyl and amino group in organic synthesis. It is used as a precursor to prepare trimethyl(2-phenoxyethyl)silanes by reacting with aromatic fluoride. It is also used in the synthesis of teoc-protected amines by using the corresponding isocyanates.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
