DESCRIPTION
General description
N-Methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) is a silylating reagent.[1]
Application
Learn more in the Product Information MSTFA may be used in silylation procedure to detemine steroid hormones 17α-ethinylestradiol (EE2) and estrone using GC-MS. MSTFA along with Trimethylsilyl chloride (TMCS) in eithyl acetate, acetonitrile and dichloromethane solvents leads to formation of trimethylsilyl (TMS) and tert-butyldimethylsilyl (TBS) derivatives.[1] Suitable for the derivatization of amines, amino acids, carboxyl, hydroxyamines, indolalkylamine, n-nitrosoamino acids, nucleosides, phenolalkylamines, serotonin and tryptamine.
Packaging
1, 1, 5, 25 mL
Other Notes
Powerful silylating agent[2][3][4][5] Reagent for N-acetyl-N, trifluoroacetyl, trimethylsilyl, N-trimethylsilyl-N-trifluoroacetyl, and O-trimethylsilyl (TMS)
