General description
N,O-Bis(trimethylsilyl)acetamide(BSA) is a powerful silylating agent for the protection of amides, amines, alcohols, carboxylic acids, enols and phenols. It can also be used as a Bronsted base precursor in Tsuji–Trost reactions. Additionally, it can be used to activate different functional groups during the production of nucleosides, peptides, and heterocycles.[1]
Application
Derivatization reagent for GC-MS analysis of phenolic acids in fruits.[2]
Reagent for the regioselective desulfation of polysaccharide sulfates.[3] Also used to prepare trimethylsilyl ethers of carbohydrates and alcohols.[4]
Features and Benefits
BSA is good moisture absorbent.[5]
