Description

Tetrasodium [mu-[[6,6'-[(3,3'-dihydroxy[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-amino-5-hydroxynaphthalene-1,3-disulphonato]](8-)]]dicuprate(4-) is a complex organic compound with a unique chemical structure, characterized by its azo and hydroxy groups. It is a type of azo dye, which is known for its ability to impart color to various substrates.

Uses

Tetrasodium [mu-[[6,6'-[(3,3'-dihydroxy[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-amino-5-hydroxynaphthalene-1,3-disulphonato]](8-)]]dicuprate(4-) is used as a dye for coloring cotton and polyester fibers in the textile industry. It is known for its green light blue color, which is achieved through its unique chemical structure.
Used in Textile Industry:
Tetrasodium [mu-[[6,6'-[(3,3'-dihydroxy[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-amino-5-hydroxynaphthalene-1,3-disulphonato]](8-)]]dicuprate(4-) is used as a cotton polyester dye for imparting green light blue color to fabrics. It is chosen for its ability to provide good colorfastness properties, such as acid resistance, alkali resistance, light fastness, and soaping.
The dye also exhibits good performance in terms of stain fading and water fading, as indicated by its ISO and AATCC ratings. These ratings are important for ensuring the durability and long-lasting color of the dyed fabrics, making it suitable for various applications in the textile industry, such as clothing, home textiles, and other textile products.

Preparation

3,3′-Dimethoxylbenzidine double nitriding, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-1,3-disulfonic acid (2 Moore) coupling, and then into copper complex.

Check Digit Verification of cas no

The CAS Registry Mumber 16143-79-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16143-79:
(7*1)+(6*6)+(5*1)+(4*4)+(3*3)+(2*7)+(1*9)=96
96 % 10 = 6
So 16143-79-6 is a valid CAS Registry Number.
