The mass spectra of 19 substituted benzothiazoles have been recorded and the identity of the various ions in the mass spectra has been established by high resolution (accurate) mass measurement. Deuterium labeling has been used to elucidate the fragmentation processes of these compounds The parent compound of the series, benzothiazole, exhibits the loss of HCN and CS from the parent ion as the most important decomposition pathways. The H atom concerned in the loss of HCN originates from the 2-position of benzothiazole, while in 2-substituted benzothiazoles, different mechanisms are apparent for the loss of HCN, and these are clarified by D labeling. Some substituted benzothiazoles can lose S from their mol. ions, a process which does not occur in benzothiazole itself. The substituted benzothiazoles undergo many other types of fragmentations, in some cases retaining the substituent, and in other cases losing it prior to collapse of the thiazole ring.
