By means of collisionally induced dissociative ionization mass spectrometry it was shown that the three isomeric aminopyridine molecular ions display ion chemistry similar to aniline molecular ions; i.e. metastable HNC loss, rather than losing the more stable neutral species HCN, behaviour typical of ionized pyridine. The molecular ions do not isomerize to a common intermediate prior to fragmentation and can readily be distinguished from their collisional activation and charge‐stripping mass spectra.
