용도
용도
N,O-Bis(trimethylsilyl)trifluoroacetamide is used for analytical purposes or as a chemical reagent for synthesis of more complex molecules. It is silylation reagent useful in GC and GC-MS for the derivatization of a wide range of functional groups under mild conditions. It is also used as DAT inhibitor and a SLC6A2 inhibitor. It is routinely used to derivatize carboxylic acids, phenols, steroids, amines, alcohols, and alkaloids and amides.
일반 설명
Bis(trimethylsilyl)trifluoroacetamide with trimethylchlorosilane has found application to be used in gas chromatography (GC) and mass-spectrometry (MS). It can also be used in HPLC- electrochemical detection assay of 8-oxo-deoxyguanosine and8-oxo-guanine.
