Application

N-tert-butyldimethylsilyl-N-methyltrifluoroacetamide (MTBSTFA) can be used:
  • As a derivatizing agent in the GC-MS analysis of hydroxylated fluorenes and in the GC analysis of amino acids.
  • As an efficient silylating agent for different alcohols, thiols, phenols, carboxylic acids, amines, and amides.
  • 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.

General description

N-tert-Butyldimethylsilyl-N-methyltrifluoroacetamide is a highly reactive silylating reagent commonly used for silyation of carboxylic acids, alcohols, amines, and thiols. It is also used as a protection, deprotection reagent.
