Electron Ionization Mass Spectra of Trimethylsilyl–Pentafluoropropionyl and Trimethylsilyl–Heptafluorobutyryl Derivatives of β-Adrenoreceptor Modulators

Resumo

The paper presents proposals for the mass spectrometric determination of β-adrenoreceptor modulators by bifunctional derivatization with N-methyl-N-(trimethylsilyl)-trifluoroacetamide followed by acylation with pentafluoropropionic or heptafluorobutyric anhydrides with a description of the derivatives obtained.
