Brand: Macherey-Nagel GmbH & Co. KGAvailable in 6 variantsN,O-bis-trimethylsilyl-trifluoroacetamidem.w. 257.4, Bp 40°C (12mm Hg), density d20°/4° = 0.961BSTFA: R = CF3 powerful trimethylsilyl donor with approximately the same donor strength as the non-fluorinated analogue BSAadvantage of BSTFA over BSA: greater volatility of its reaction products (particularly useful for GC of some lower boiling TMS amino acids.BSTFA is nonpolar (less polar than MSTFA), and can be mixed with acetonitrile for improved solubility. For silylating fatty acid amides, hindered hydroxyls and other compounds, which are difficult to silylate (like secondary alcohols and amines), we recommend BSTFA + 1% trimethylchlorosilane (TMCS), available under the designation SILYL-991.
