Descripción general

MSTFA (N-Methyl-N-trimethylsilylfluoroacetamide) is an important trimethylsilyl reagent, and a commonly applied reagent since it is highly reactive towards a broad range of compound classes. GC-MS optimization studies reveal the use of this reagent either alone or in combination with 1% of trimethylchlorosilane as a catalyst for silylation of complex mixtures. It has similar reactivity as BSA and BSTFA.

Aplicación

MSTFA reagent may be used as a derivatizing agent in the following:
  • Analysis of estrogen steroids such as estrone (E1), 17α-ethinylestradiol (EE2), and trenbolone acetate metabolites, melengestrol in environmental matrices using gas chromatography coupled to mass spectrometry (GC-MS).
  • Quantification of ibuprofen, naproxen, ketoprofen, and diclofenac in wastewater samples using gas chromatography coupled to mass spectrometry (GC-MS).

Características y beneficios

  • Very volatile of TMS-acetamides.
  • More volatile than BSA or BSTFA but with similar silylation strength.
  • Useful in the analysis of volatile trace materials.
  • Used in the preparation of volatile and thermally stable derivatives for GC and MS analysis.
