Determination of 1,3-diphenyltriazene and azobenzene in D&C Red No. 33 by solvent extraction and reversed-phase high-performance liquid chromatography.

J E Bailey

Journal of chromatography, 321(1), 185-197 (1985-03-08)

Data are presented for the determination of trace levels of 1,3-diphenyltriazene (DPT) and azobenzene (AB) in D&C Red No. 33. The contaminants are extracted with chloroform from an aqueous solution of the color, and the chloroform is removed under vacuum.

Micronucleus induction in mice exposed to diazoaminobenzene or its metabolites, benzene and aniline: implications for diazoaminobenzene carcinogenicity.

Nancy B Ress et al.

Mutation research, 521(1-2), 201-208 (2002-11-20)

Diazoaminobenzene (DAAB), a manufacturing intermediate metabolized primarily to the known carcinogens benzene and aniline, has been identified as an impurity in a number of dyes and coloring agents that are components of cosmetics, food products, and pharmaceuticals. Several structural analogs

Reduction of 1,3-diphenyl-1-triazene by rat hepatic microsomes, by cecal microflora, and in rats generates the phenyl radical metabolite: nn ESR spin-trapping investigation.

M B Kadiiska et al.

Chemical research in toxicology, 13(11), 1082-1086 (2000-11-23)

An ESR spin-trapping technique was used to determine whether free radical metabolites are formed as a result of the reduction of 1, 3-diphenyl-1-triazene (DPT) in vivo and in vitro by components of the cytochrome P450 (P450) mixed-function oxidase system in
