What is tetrasodium [4-acetamido-5-hydroxy-6-[[2-hydroxy-4-[[4-[2-[4-[(4-methoxyphenyl)azo]-2-sulphophenyl]vinyl]-3-sulphophenyl]azo]-6-sulpho-1-naphthyl]azo]naphthalene-1-sulphonato(6-)]cuprate(4-)?

Preparation

2-(2-Sulfo-4-nitrostyryl)-5-aminobenzenesulfonic acid diazo, coupled with phenol, then methylation, will the Nitro reduction, product diazo, and 5-Amino-7-ehtoxy-2-naphthalenesulfonic acid coupling, its product to diazo, and 8-Acetamido-1-naphthol-5-sulfonic acid coupling, and finally into copper complex. In the copper complexation processes,?ethoxy group may be substituted with hydroxy.
