Gas chromatographic mass spectrometric identification of N-dicarboxylmonoglycines.

A number of N-dicarboxylmonoglycines of biological interest have been synthesized. They were characterized by means of mass spectrometry. Gas chromatography of the methyl esters of methylmalonyl-, succinyl-, glutaryl-, adipyl-, suberyl- and sebacylglycines showed a single sharp peak for each compound on Dexsil 300 and OV-17 columns. Methylene unit values and mass spectra of the six methyl esters are reported.
