Abstract:L-Glutamine was treated at high temperature and separated by preparative chromatography. The structure of the impurity was analyzed by 1H NMR, 13C NMR and LC-MS. The compound was identified as N-acetyl-L-glutamine. The impurity can be used as the reference substance in the research of L-glutamine. |
Key words:glutamine; structural confirmation; N-acetyl-L-glutamine |
