Formation of radical anions of radiosensitizers and related model compounds via electrospray ionization

- Radical anions of nimorazole and misonidazole were observed for the first time.
- Key finding is that radical anions are directly formed via electrospray ionization.
- First report of fragmentation of positive and negative ions of radiosensitizers.
- The fragmentation depends on the nature of the charge.
- Misonidazole shows more complex fragmentation than nimorazole.
