Specification

The Acid Green 41, with the cas register number 4430-16-4, has its systematic name of [2-[[5,8-dihydroxy-4-[(4-methyl-2-sodiooxysulfonyl-phenyl)amino]-9,10-dioxo-1-anthryl]amino]-5-methyl-phenyl]sulfonyloxysodium dark green crystalline powder. This chemical belongs to the category of Dyes and Pigments. When contact with this chemical, avoid contacting with skin and eyes.

This chemical is a kind of green powder, and is soluble in water, acetone, ethanol, Ethylene Glycol, o-chlorophenol, and pyridine. But it is insoluble in benzene, carbon tetrachloride, chloroform and methylbenzene. The color is green in concentrated sulfuric acid and then turn into light green.

The characteristics of this chemical are as following: (1)#H bond acceptors: 12; (2)#H bond donors: 4; (3)#Freely Rotating Bonds: 12; (4)Polar Surface Area: 202.16; (5)Tautomer Count: 95; (6)Exact Mass: 608.055936; (7)MonoIsotopic Mass: 608.055936; (8)Topological Polar Surface Area: 230; (9)Heavy Atom Count: 42; (10)Formal Charge: -2; (11)Complexity: 1130.

When it comes to the production method, you could follow the below steps. Prepare the material of 1,4,5,8-tetrahydroxyanthracenequinone and paratoluidine, and then restore part of the 1,4,5,8-tetrahydroxyanthracenequinone with zinc powde and hydrochloric; Next, condense with paratoluidine, and then sulfonate and neutralize to get the crude; Finally, go through a listing process of salting out, filtering, drying and smashing to get the products.

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

In addition, you could convert the following datas into the molecular structure：
(1)SMILES:[Na]OS(=O)(=O)c5cc(C)ccc5Nc4ccc(Nc1ccc(C)cc1S(=O)(=O)O[Na])c3C(=O)c2c(O)ccc(O)c2C(=O)c34
