Usage

General Description

4-(Methylamino)azobenzene is a chemical compound that belongs to the azobenzene class of compounds. It is a member of the azo dye family and is commonly used in various industrial applications, including as a dye for textiles, as a colorant in plastics and rubber products, and as a reagent for organic synthesis. 4-(Methylamino)azobenzene is known for its vibrant yellow to orange-red color and is often used in the production of yellow dyes. It is considered to be relatively stable and has low solubility in water, but it is soluble in organic solvents. The chemical structure of 4-(Methylamino)azobenzene consists of a benzene ring with an azo group (-N=N-) and a methylamino group (-N(CH3)-) attached, giving it its unique properties and applications. It is important to handle 4-(Methylamino)azobenzene with care, as it may be toxic and harmful if not properly managed.

ELECTROCHEMICAL AND CHEMICAL OXIDATION OF SOME AZO DYES

The oxidation potential of representative azo dyes, viz. a series of N,N-dialkylaminoazo dyes 1 and of tautomeric azonaphthols (2 and 5) has been determined.Anodic oxidation and chemical oxidation have been carried out for some of the dyes.The results are rationalized as involving a single intermediate, the radical cation of the dyes, and its evolution along two main pathways, viz. a) deprotonation whenever possible (from the α position of the N-alkyl group in aminoazo dyes, leading ultimately to N-dealkylation; fromthe naphthols to eventually yield a C-C-coupled dimer) and b) heterolytic cleavage to an aryl radical and a diazonium cation, the latter trapped under favourable conditions to yield a bisazodye.
