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.
