Description

Diethoxydimethylsilane is useful for blocking hydroxyl and amino groups in organic synthesis reactions. This silylating step allows subsequent reactions to be carried out which would be adversely affected by the presence of active hydrogen in the hydroxyl or amine groups. Following the reaction step, hydroxyl or amine groups blocked with diethoxydimethylsilane may be recovered by a hydrolysis procedure. It is also used for preparing hydrophobic and release materials as well as enhancing flow of powders.

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.
