| Abstract: | The molecular weights of a series of 1H-2,3-dihydro-1-pyrrolizinone derivatives have been rapidly determined by LDI-TOF-MS. Some MS rules of these compounds were concluded.No matrix needed to assist the desorption/ionization processes of the samples. It was satisfying that the experimental values were identical with the theoretical values. The results demonstrated that LDI-TOF-MS was a rapid, simple and accurate method for the molecular weight determination of 1H-2,3-dihydro-1-pyrrolizinone derivatives. |
| Keywords: | LDI-TOF-MS 1H-2 3-dihydro-1-pyrrolizinone derivatives |
