Definition:A member of the class of azobenzenes that is azobenzene in which one of the phenyl groups is substituted at the para position by a sulfo group, while the other is substituted at a meta position by a sulfo group and at the para position by an amino group. The disodium salt is the biological stain 'fast yellow'.
