| | Mstfa Reagent Usage And Synthesis |
| Chemical Properties | Clear colorless to light yellow liquid | | Uses | A new metabolite of Famprofazone in humans. | | Uses | N-Methyl-N-(trimethylsilyl)trifluoroacetamide is used as a silylating reagent that forms volatile derivatives for GC-MS analysis. It acts as a pharmaceutical intermediate and metabolite of Famprofazone in humans. It is also used in the detection of steroid hormones 17-alfa-ethynylestradiol and estrone. | | Definition | ChEBI: An N-silyl compound that is N-methyltrifluoroacetamide in which the amide nitrogen is replaced by a trimethylsilyl group. N-methyl-N-(trimethylsilyl)trifluoroacetamide is a derivat
sation agent used in gas chromatography/mass spectrometry applications. | | General Description | N-Methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) is a derivatizing reagent. It can be used as alternatives to diazomethane. | | Purification Methods | Fractionate the amide through a 40mm Vigreux column (p 11). Usually it contains ca 1% of methyl trifluoroacetamide and 1% of other impurities which can be removed by gas chromatography or fractionating using a spinning band column.
