    Application

    BSTFA (with 1% TMCS) may be used as a derivatizing agent in the following:
    • Analysis of estrogenic compounds in water samples using gas chromatography coupled to mass spectrometry (GC-MS).[1]
    • Quantification of α-pyrrolidinovalerophenone (α-PVP) and its metabolites in urine samples using gas chromatography coupled to mass spectrometry (GC-MS).[2]

    Features and Benefits

    • BSTFA is very versatile, reacting with a range of polar organic compounds and replacing active hydrogens with a −Si(CH3)3 (trimethylsilyl) group.
    • Reacts rapidly and more completely than BSA.;
    • TMCS increases the reactivity of BSTFA (or other silylation reagents).
    • Amides and many secondary amines and hindered hydroxyls, incompletely derivatized by BSTFA alone, can be derivatized by adding 1-20% TMCS to BSTFA.
    • Has good solvent properties and can function as a silylation reagent without additional solvents.
    • Alternatively, the mixture is very soluble in most commonly used silylation solvents.
