Product Description	Application N - tert -butyldimethylsilyl- N -methyltrifluoroacetamide (MTBSTFA) can be used as an efficient silylating agent for different alcohols, thiols, phenols, carboxylic acids, amines, and amides. It can also be used to functionalize multi-walled carbon nanotubes (MWCNTs) with polar groups. MTBSTFA is reportedly much less moisture-sensitive than other silylating reagents used for GLC derivatization.
