BSTFA-TMCS
The combination of BSTFA and TMCS is the preferred reagent for trimethylsilylation of alcohols, alkaloids, amines, biogenic amines, carboxylic acids, phenols, and steroids. TMCS increases the reactivity of BSTFA. BSTFA-TMCS has good solvent properties and can function as a silylation reagent without additional solvents.
