Mass spectra of N(O,S)-isobutoxycarbonyl isobutyl esters of 17 amino acids (L-alanine, glycine, L-valine, L-norvaline, L-leucine, L-isoleucine, L-norleucine, L-proline, L-asparagine, L-methionine, L-threonine, L-serine, L-phenylalanine, L-lysine, L-tryptophan, L-tyrosine and L-cystine) were obtained in the electron ionization mode. These derivatives were found suitable for the analysis of amino acids in aqueous media allowing proper identification and quantitation from the mass spectral characteristics.
