clear light yellow liquid | [Uses]
N-Methyl-N-trimethylsilylacetamide may be used as a derivatizing reagent for the following:???????
- Quantification of the carbohydrate intermediates in glycation systems using gas chromatography coupled to mass spectrometry technique.???????
- Characterization of damaged products of thymine and cytosine formed by the exposure to UV light in a hydrogen peroxide solution using gas chromatography/mass spectrometry with scan mode and selected ion monitoring mode.
| [Reactions]
The interaction of N-Methyl-N-(trimethylsilyl)acetamide with chloromethyl(methyl)-diacetoxysilane led to the formation of 2,4,6-trimethyl-2,4-bis((N-methylacetamido)methyl)-1,3,5,2,4-trioxadisilinan-6-ylium chloride[1].
| [General Description]
N-Methyl-N-trimethylsilylacetamide is a trialkyl-silyl reagent and a versatile derivatizing agent used in gas chromatography (GC). | [Purification Methods]
N-Methyl-N-trimethylsilylacetamide [7449-74-3] M 145.3, b 48 -49o/11mm, 8 4o/13mm, 105-107o/35mm (solid at room temperature), d 4 0.90, n D 1.4379. A likely impurity is Et3N.HCl which can be detected by its odour. If it is completely soluble in *C6H6, then redistil; otherwise dissolve it in this solvent, filter and evaporate first in a vacuum at 12mm, then fractionate; all operations should be carried out in a dry N2 atmosphere.
