설명

일반 설명

N,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA) is an excellent silylation reagent. For some sterically hindered primary or secondary nitro compounds, N,O-bis(trimethylsilyl)acetamide and BSTFA achieve better results than normal silylation conditions. BSTFA finds application in derivatizing amines. It is suitable for silyaltion of carboxylic acids, phenols, ureas, amides and alcohols.

애플리케이션

Learn more in the Product Information

BSTFA + 1% TMCS (trimethylsilyl) in ethyl acetate, acetonitrile and dichloromethane solvents may be used for silylation of steroid hormone 17a-ethinylestradiol (EE2) using gas chromatography-mass spectrometry (GC-MS). It may also be used for silylation of endogenous 2-monoglyceride, present in canine gut that binds to cannabinoid receptors.
