title: [Formation of an azoderivative of phenothiazine].
abstract: The reaction of phenothiazine-5-oxide in 2 N HCl with 2,4-dinitrophenylhydrazine gives rise to 3-azo-(2',4'-dinitrophenyl)phenothiazine and phenothiazine. The stoichiometric ratio is two molecules of phenothiazine-5-oxide to one molecule of 2,4-dinitrophenylhydrazine.
