摘要
Abstract Electron impact (EI), chemical ionization and negative‐ion chemical ionization (NCI) mass spectra of 1,4‐dinitroglycoluril (DINGU), its 15 N‐ and 2 H‐labeled analogues and the dimethyl‐substituted derivatives were recorded. Tandem mass spectrometry with collision induced dissociation was used to study the fragmentation pathways of these compounds. It was found that the main EI fragmentation processes of DINGU are due to the cleavage of CN bonds and some rearrangement reactions.
