应用
N,O-Bis(trimethylsilyl)acetamide is used as a regioselective desulfation reagent as well as a preparatory agent for carbohydrate and alcohol trimethylsilyl ethers. It is also used for the derivatization of polar functional groups such as carboxylic acids, phenols, steroids, amines, alcohols, alkaloids and amides. It is employed in the formation of stable trimethylsilyl derivatives. Further, it is used in analytical chemistry for the derivatization of compounds in analysis to increase their volatility and to introduce the trimethylsilyl protecting group in organic synthesis. In addition to this, it is used in the protection of hydroxyl groups in natural products, functional groups in organic intermediates and derivatization reagent for gas chromatography-Mass spectral analysis of phenolic acids in fruits.
