Diisopropyl 3,3′-[(2,5-dichloro-1,4-phenylene)bis[iminocarbonyl(2-hydroxy-3,1-naphthylene)azo]]bis[4-methylbenzoate] CAS#71566-54-6

Diisopropyl 3,3′-[(2,5-dichloro-1,4-phenyl)bis[iminocarbonyl(2-hydroxy-3,1-naphthyl)azo]]bis[4-methylbenzoate] (CAS: 71566-54-6) is a dye.
It has a specific chemical structure, which contains azo groups, benzene rings, naphthalene rings, etc., which gives it the characteristics of a dye and can be used to dye various materials to give them a specific color.
Dyes usually bind to the dyed material by adsorption, penetration or chemical reaction, thereby changing the color of the dyed material. The specific color performance may be affected by factors such as the concentration of the dye, the medium used, and the nature of the dyed material.
