General description

N-Methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) is a silylating reagent.

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.
Suitable for the derivatization of amines, amino acids, carboxyl, hydroxyamines, indolalkylamine, n-nitrosoamino acids, nucleosides, phenolalkylamines, serotonin and tryptamine.

Other Notes

Powerful silylating agent
Reagent for N-acetyl-N, trifluoroacetyl, trimethylsilyl, N-trimethylsilyl-N-trifluoroacetyl, and O-trimethylsilyl (TMS)

Glucosinolates are defense-related secondary metabolites found in Brassicaceae. When Brassicaceae come under attack, glucosinolates are hydrolyzed into different forms of glucosinolate hydrolysis products (GHPs). Among the GHPs, isothiocyanates are the most comprehensively characterized defensive compounds, whereas the functional study of
