Report on carcinogens : carcinogen profiles, 12, 132-134 (2011-08-19)

Gold nanoparticles modified electrode via a mercapto-diazoaminobenzene monolayer and its development in DNA electrochemical biosensor.

Feng Li et al.

Biosensors & bioelectronics, 25(9), 2084-2088 (2010-03-09)

A novel protocol for the gold nanoparticles (AuNPs) modification on the electrode surface was proposed, which was based on the self-assembly of AuNPs on the mercapto-diazoaminobenzene monolayer modified electrode. The mercapto-diazoaminobenzene monolayer was obtained by covalent immobilization of 4-aminothiophenol (4-ATP)

A ligand-free copper (1) catalysed intramolecular N-arylation of diazoaminobenzenes in PEG-water: an expeditious protocol towards regiospecific 1-aryl benzotriazoles.

Chhanda Mukhopadhyay et al.

Organic & biomolecular chemistry, 8(20), 4720-4729 (2010-09-08)

An efficient and highly versatile method for the synthesis of diverse regiospecific 1-arylbenzotriazoles being important medicinal scaffolds, by the copper (1) catalysed intramolecular N-arylation of diazoaminobenzenes of 2-haloaryldiazonium salts in PEG-water has been developed. A very simple reaction protocol, large

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
