Acylation reagents for GC - Bisacylamides | Description: MBTFA, Capacity ml: 1
Merk: Macherey-Nagel GmbH & Co. KGBeschikbaar in 3 variantenAcylation with fluorinated acid amides is recommended for alcohols, primary and secondary amines as well as for thiols under mild, neutral conditions. MBTFA also forms very volatile derivatives with carbohydrates.by-products: corresponding neutral acylamides, which can be easily removed due to their high volatility; because of neutral conditions and favourable chromatographic properties often removal of the bisacylamide is not necessary. Thus sample preparation is much more convenient.MBTFA / MBHFBAN-methyl-bis(trifluoroacetamide) MBTFAm.w. 223.08, Bp 123 - 124°C (760mm Hg), density d20°/4° = 1.55,CF3 - CO - N(CH3) - CO - CF3
