Beskrivelse

Complete silylation reactions with high reaction rates, even without a catalyst. MSTFA Silylation Reagent is the most volatile trimethylsilyl amide available.

  • N-methyl-N-trimethylsilyl-trifluoroacetamide
  • M 199.1g/mol, Bp 70°C (75 mm Hg), density d20°/4° = 1.11
  • MSTFA: R' = CF3, R″ = CH3
  • The most volatile trimethylsilyl amide available
  • Very strong TMS donor which does not cause any noticeable FID fouling even after long-time measuring series
  • The already good solution characteristics can be improved by addition of submolar quantities of protic solvents (e.g., TFA for extremely polar compounds such as hydrochlorides) or pyridine (e.g., for carbohydrates).
  • Recommended application: carboxylic acids, hydroxy and ketocarboxylic acids, amino acids, amines, alcohols, polyalcohols, sugars, mercaptans and similar compounds with active hydrogen atoms. Even amine hydrochlorides can be silylated directly.
  • Advantages: complete reaction with high reaction rates, even without a catalyst (1–2 % TMCS or TSIM)
  • The by-product of the reaction (N-methyltrifluoroacetamide) features high volatility and short retention time.
