Applications
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.

Solubility
Reacts with water.

Notes
Store under dry inert gas. It is sensitive to moisture. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents
