화학적 성질
WHITE TO YELLOWISH CRYSTALLINE MASS용도
N-Trimethylsilylacetamide is a silylating agent used in organic synthesis. N-Trimethylsilylacetamide is used in the preparation of the antibacterial agent Cefdinir (C242670).일반 설명
The efficiency of N-(Trimethylsilyl)acetamide (TMS acetamide) as allyl group scavenger and its compatibility with Fluorenylmethyloxycarbonyl chloride (Fmoc) protecting groups were studied.Purification Methods
Distil the amide repeatedly in an inert atmosphere with all operations to be performed in an anhydrous atmosphere. In the presence of moisture, trimethylsilanol (b 31-34o/26mm) is formed and is a likely impurity (check by NMR). [Birkofer et al.
