Usage

General Description

4-chloro-4'-methoxy-2-nitroazobenzene is a chemical compound that is commonly used as a dye intermediate. It is a yellow to orange crystalline powder that is insoluble in water but soluble in organic solvents. It is classified as an azo compound, which contains a nitrogen-nitrogen double bond. This chemical is primarily utilized in the production of dyes, pigments, and colorants for textiles, plastics, and other materials. However, it should be handled with caution as it is considered to be a hazardous substance with potential health and environmental risks.

Preparation of Some 2-(Methoxyphenyl)-2H-benzotriazoles and the Corresponding Hydroxyphenyl Compounds

The reaction of several substituted o-nitronitrosobenzenes with o- and p-anisidine, and 2,4-dimethoxyaniline in acetic acid gives in good yield the corresponding o-nitroazobenzenes which are readily reduced with thiourea dioxide (formamidinesulfinic acid) to the corresponding 2-(methoxyphenyl)-2H-benzotriazoles, demethylation of which furnished the corresponding 2-(hydroxyphenyl)-2H-benzotriazoles.Demethylation of the dimethoxy derivatives was best accomplished with boron tribromide in methylene chloride, the methoxy group located ortho to the benzotriazole ring beingdemethylated more readily than is the para-methoxy group.The reaction of 0-nitroazobenzenes containing a methoxy group with hydrobromic acid in acetic acid results in cleavage of the azo bond and also partial bromination to give o-nitroaniline and some of its brominated derivatives.
