    AZOBENZENE is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized . Dapsone has also been used to treat coccidiosis in cattle. Dapsone passed the human and animal data screens, underwent a preliminary toxicological evaluation, and is being brought to the Carcinogen Identification Committee for consultation. This is a compilation of the relevant studies identified during the preliminary toxicological Size: 39KB.

A bioassay of azobenzene for possible carcinogenicity was conducted by administering the test chemical in feed to F rats and B6C3F1 mice.

Groups of 50 rats of each sex were administered azobenzene at one of two doses, either or ppm, for or weeks. Matched controls consisted of 20 untreated rats of each sex. An overview of Genetic Toxicology Drosophila Germ Cell Mutagenicity study conclusions related to Azobenzene ().

Groups of 50 rats of each sex were administered azobenzene at one of two doses, either or ppm, for or weeks. Matched controls consisted of 20 untreated rats of each sex. Most azobenzene-based photoswitches use UV light for photoisomerization. This can limit their application in biological systems, where UV light can trigger unwanted responses, including cellular apoptosis.

We have found that substitution of all four ortho positions with methoxy groups in an amidoazobenzene derivative leads to a substantial (∼35 nm) red shift of the n−π* band Cited by:   The sonochemical degradation of azobenzene and related azo dyes: rate enhancements via Fenton's reactions.
