Thermo Scientific™ BSTFA Silylation Reagent

Descrizione

Improve GC analysis with Thermo Scientific™ BSTFA Silylation Reagent. The highly volatile byproducts mono(trimethylsilyl)trifluoroacetamide (BSTFA) and trifluoroacetamide elute with the solvent front to ensure excellent chromatographic separations. This silylation reagent reacts with a wide range of polar compounds and is particularly well suited for the GC analyses of some lower boiling TMS-amino acids and TMS Krebs cycle acids.

BSTFA is a powerful thrimethylsilyl donor, with donor strength that is comparable to its unfluorinated analog BSA [N,O-Bis(trimethylsilyl)acetamide]. BSTFA reacts to replace labile hydrogens on a wide range of polar compounds with a -Si(CH₃)₃ group. This physical characteristic is particularly useful in the gas chromatography of some lower boiling TMS-amino acids and TMS Krebs cycle acids.

• Increased volatility of reaction byproducts mono(trimethylsilyl)trifluoroacetamide and trifluoroacetamide over corresponding nonfluorinated compounds from BSA
• Increased volatility makes it possible to derivatize smaller molecules with which the TMS derivatives elute with the byproducts from BSA
