The molecule is an imine that is 4-methylidenecyclohexa-2,5-dien-1-imine in which the hydrogens of the methylidene group are replaced by 4-aminophenyl and 3-methyl-4-aminophenyl groups. The monohydrochloride salt is the histological dye 'rosanilin'. It has a role as a histological dye, a fluorochrome and a carcinogenic agent. It is an imine and a substituted aniline. It is a conjugate base of a rosanilin(1+).
