Usage

Definition

ChEBI: A member of the class of azobenzenes that is azobenzene in which one of the phenyl groups is substituted at position 3 by a methyl group, while the other is substituted at position 4 by a dimethylamino group. It is a potent liver carcinogen.

Safety Profile

Moderately toxic by ingestion. An experimental teratogen. Questionable carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx

Synthesis of new azo dyes under phase-transfer catalysis

New azo dyes that do not enter into azo coupling reactions under classical conditions (water solutions, polar organic solvents) were prepared by nontraditional method (in solutions in 1,2-dichloroethane and chloroform and in water emulsions thereof) with the use of phase-transfer catalysts (dibenzo-18-crown-6, benzyltrimethylammonium chloride, sodium 4-dodecylbenzenesulfonate). The azo dyes obtained: 4-(3-nitrophenylazo)-1-bromo-2-methoxynaphthalene, 4-(3-methylphenylazo)-1-bromo-2-methoxynaphthalene, 3-nitrophenylazochrysene, 3-methylphenylazochrysene were produced in high yields and showed good processing properties.
