23211-47-4 Usage
Uses
Used in Textile Industry:Reactive Red 3 is used as a coloring agent for dyeing fabrics, providing a rich red hue and enhancing the visual appeal of the textile products. Its good solubility in water allows for easy application and even distribution of the dye.
Used in Color Fastness:
Reactive Red 3 is utilized to improve the light fastness, oxygen bleaching, perspiration fastness, and soaping of dyed fabrics. It helps maintain the color intensity and prevents fading under various conditions, ensuring the durability and longevity of the textile products.
Standard:
The performance of Reactive Red 3 in terms of color fastness is measured according to the ISO standard. It has achieved a rating of 5 for light fastness, 4 (light blue) for oxygen bleaching, and 4-5 for both perspiration fastness and soaping. These ratings indicate the dye's ability to resist fading and staining under different environmental factors.
Preparation
2-Aminobenzenesulfonic acid diazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, and then and 2,4,6-Trichloro-1,3,5-triazine condensation, again with aniline condensation.Standard

5Check Digit Verification of cas no
The CAS Registry Mumber 23211-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,1 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.Calculate Digit Verification of CAS Registry Number 23211-47:
(7*2)+(6*3)+(5*2)+(4*1)+(3*1)+(2*4)+(1*7)=64
64 % 10 = 4
So 23211-47-4 is a valid CAS Registry Number.
