N-Methyl-N-(trimethylsilyl)trifluoroacetamide Chemical Properties,Usage,Production
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.
