N-(tert-Butyldimethylsilyl)-N-methyltrifluoroacetamide (MTBSTFA) réactif de silylation, pour dérivatisation GC
N-(tert-Butyldimethylsilyl)-N-methyltrifluoroacetamide (MTBSTFA)
MBDSTFA is a silylation reagent that donates a tert-butyldimethylsilyl group (TBDMS) for derivatizing active hydrogen atoms in hydroxyl, carboxyl and thiol groups, primary and secondary amines as well as amino acids. Fast reactions (typically 5–20 min) with high yields (> 96 %). By-products are neutral and volatile.
- Silylation can be applied on many compounds
- Silylation reagents are easily prepared
- MBDSTFA derivatisation has a fast reaction time
TBDMS ethers are 10⁴ times more stable than the corresponding TMS ethers. Chromatographic retention times are longer due to the large protecting group, which may improve some separations. Very useful for GC-MS applications, because of the high molecular ion concentration at M+-57.
