6420-36-6 Usage
Uses
Used in Textile Industry:
3,3'-[Carbonylbis[imino(5-methoxy-2-methyl-4,1-phenylene)azo]]bis[5-[(3-aminobenzoyl)amino]-4-methylbenzenesulfonic acid sodium] salt is used as a dye for cellulose fibers and silk. It is particularly effective for dyeing cellulose fibers, with a maximum affinity at 80°C. The dye exhibits good acid and alkali resistance, as well as light fastness, making it a reliable choice for long-lasting color in textiles.
Used in Leather Industry:
In addition to its application in the textile industry, 3,3'-[Carbonylbis[imino(5-methoxy-2-methyl-4,1-phenylene)azo]]bis[5-[(3-aminobenzoyl)amino]-4-methylbenzenesulfonic acid sodium] salt can also be used for leather coloring. Its properties, such as acid and alkali resistance, contribute to the durability and color stability of the leather products.
Standard:
The standard for this dye includes the following properties:
Acid Resistance: AATCC 5
Alkali Resistance: AATCC 3-4
Light Fastness: AATCC 2
Soaping: AATCC 3-4
Water Fading: AATCC 5
Stain Fading: AATCC 5
These standards ensure that the dye meets the required quality and performance criteria for its various applications in the textile and leather industries.
Preparation
3-Amino-4-methyl-5-(3-aininobenzamido)benzenesulfonic acid nitro reduction for the yankees nitrogen, with sodium sulfite chlorine processing, make it become the amino sulfonic acid. Product diazo, and 2-Amino-4-methylanisole coupling, and then make the light gasification, finally hydrolysis amino sulfonic acid base

Check Digit Verification of cas no
The CAS Registry Mumber 6420-36-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6420-36:
(6*6)+(5*4)+(4*2)+(3*0)+(2*3)+(1*6)=76
76 % 10 = 6
So 6420-36-6 is a valid CAS Registry Number.
