CAS 126889-55-2: Trifluoromethanesulfonicaciddiethylisopropylsilylester
Description:Trifluoromethanesulfonic acid diethylisopropylsilyl ester, identified by its CAS number 126889-55-2, is a chemical compound characterized by its strong acidity and reactivity, typical of trifluoromethanesulfonic acid derivatives. This compound features a trifluoromethanesulfonyl group, which imparts significant electrophilic character, making it useful in various organic synthesis applications, particularly in the formation of sulfonate esters. The presence of the diethylisopropylsilyl moiety enhances its stability and solubility in organic solvents, facilitating its use in reactions that require a stable silyl protecting group. Additionally, the trifluoromethyl group contributes to its unique properties, such as increased lipophilicity and potential applications in pharmaceuticals and agrochemicals. Due to its strong acidic nature, it must be handled with care, as it can react vigorously with bases and nucleophiles. Overall, this compound serves as a valuable reagent in synthetic chemistry, particularly in the context of silylation and functional group transformations.
