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.
Application
Reagent for the regioselective desulfation of polysaccharide sulfates. Also used to prepare trimethylsilyl ethers of carbohydrates and alcohols.
Derivatization reagent for GC-MS analysis of phenolic acids in fruits.
Features and Benefits
BSA is good moisture absorbent.
