Mass spectrometric identification of aldonolactones as trimethylsilyl derivatives

• Trimethylsilyl ethers of aldonolactones are useful for the identification of aldonic acids by mass spectrometry. Peaks recorded for the molecular ion (M) and for mass M-15 give a reliable determination of the molecular weight. Significant differences exist between 1,4- and 1,5-lactones. All diastereomers studied can be well distinguished from each other.
