The mass spectrograms of 10‐chloro‐ and 10‐methyl‐5,10‐dihydrophenarsazine have been determined. These spectrograms show the following main characteristics of fragmentation behavior for these heterocycles: (a) a relative stability, in both compounds, of the arsenic atom within the heterocyclic framework; (b) an exceptionally facile splitting of the As‐Cl bond, contrasting with the behavior of the As‐CH 3 bond; and (c) an easy formation of the phenarsazine species from 10‐chloro‐5,10‐dihydrophenarsazine.
