Agent and process for the determination of redox systems

Abstract

Abstract The present invention is concerned with aniline derivatives of the general formula: <IMAGE> (I) wherein R1 is hydrogen or a lower alkyl or aryl, R2 is hydrogen or a lower alkyl which can be substituted by hydroxyl, amino carboxyl, lower alkoxycarbonyl, lower alkanoylamide lower alkyl or aryl or by a group of the structure <IMAGE> is which R5 and R6 have the meanings given hereinafter, R3 is a hydrogen or halogen atom or a carboxyl group, R4 and R'4, which can be the same or different, are hydrogen or halogen, carboxyl or lower alkoxy or lower alkyl radicals which are preferably in the m-position, R5 is hydrogen or a lower alkyl and R6 is hydroxyl or a lower alkoxy, lower alkyl or aryl radical; and of the salts thereof with acids and bases useful as a color former in the Trinder reaction for the detection of hydrogen peroxide or hydrogen peroxide-forming systems or peroxidase or peroxidate-acting substances or together with an oxidation agent for the detection of aromatic amines or of systems forming such amines.
