Six dipyrido[1,2‐ a :3′,2′ d ]imidazole derivatives related to glutamic acid pyrolysates have been studied by mass spectrometry. The data indicate that there are certain ions which are characteristic of the fragmentation of this family of compounds under electron impact. These compounds should thus be amenable to analysis if they were produced during the combustion of foods. In addition, electronolysis of L‐glutamic acid was also studied: the fragmentation pattern of the latter has shown the formation of some known dipyridoimidazoles for temperatures higher than 100°. Similarities between pyrolysis and electronolysis of this acid are discussed.
