BSTFA GC Silylation Reagent, 1 ml ampule, 10 pc/pak

Trimethylsilyl 2,2,2-trifluoro-N-(trimethylsilyl)acetimidate

BSTFA is a powerful trimethylsilyl donor with donor strength comparable to that of its non-fluorinated analog, BSA [N,O-bis(trimethylsilyl)acetamide]. BSTFA reacts by replacing labile hydrogens with a -Si(CH3)3 group in a wide range of polar compounds. This physical property is particularly useful in the gas chromatography of some TMS amino acids and TMS citrate cyclic acids with low boiling points.
Increased volatility of the reaction byproducts mono(trimethylsilyl)trifluoroacetamide and trifluoroacetamide relative to corresponding non-fluorinated BSA compounds
Increased volatility enables the derivatization of small molecules with which the TMS derivatives co-elute with the byproducts of BSA.
