Description
Clear to yellowish clear liquid liquid which is soluble in many nonpolar and polar aprotic solvents. The trimethylsilyl group is a frequently utilized monofunctional blocking group for protic organic and inorganic materials. As it eliminated during the silylation is neutral acetamide, N,O-Bis(trimethylsilyl)acetamide can be preferably used for substrates which are acid- or base-sensitive. N,O-bis(trimethylsilyl)-acetamide is an effective silylating agent.
