Specification

The Acid Dark Green A, with the cas register number 5850-39-5, has its systematic name of disodium 4-amino-3-(4-aminophenyl)azo-5-hydroxy-6-phenylazo-naphthalene-2,7-disulfonate. This is a kind of dark blue to dark black powder and is soluble in water, Ethylene Glycol, ethanol but insoluble in other organic solution . The color is blue light in the water solution while is purple in strong caustic. And its product categories are including organics.

When it comes to the production method, you could follow the below steps. firstly, prepare the material of nitroaniline, H acid, aniline; Secondly, couple the nitroaniline and H acid for the first time, and then diazotize the aniline; have the second coupling of mono azo compound; Then, restore the nitro products with sodium sulfide to get the crude; Lastly, go through the process of salting out, filtering, and smashing to get the products.

As to its usage, it is widely applied in many ways. It could be used in the dyeing of wool, silk and blend fabric; It could also be used in the direct printing of silk, wool and nylon; Besides, it could be used in the dyeing of leather and paper.

In addition, you could convert the following datas into the molecular structure：
SMILES: [Na+].[Na+].Nc1ccc(cc1)N=Nc2c(N)c4c(cc2S([O-])(=O)=O)cc(c(N=Nc3ccccc3)c4O)S([O-])(=O)=O
