General description

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.[1] BSTFA finds application in derivatizing amines.[2] It is suitable for silyaltion of carboxylic acids, phenols, ureas, amides and alcohols.[3]

Application

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).[4] It may also be used for silylation of endogenous 2-monoglyceride, present in canine gut that binds to cannabinoid receptors.[5]
