Application

N-tert-Butyldimethylsilyl-N-methyltrifluoroacetamide with 1% tert-butyldimethylchlorosilane is commonly used for the preparation of N-tert-butyldimethylsilyl ethanolamines resulting from the hydrolysis of nitrogen mustards. It is also used for selective O-silylation of N,O-diacylhydroxyl amines.
