Description
Reactive Red 221 is a rose red powder that exhibits a colorful red-blue hue. It is soluble in water and is known for its light fastness, oxygen bleaching resistance, perspiration fastness, and soaping properties.Uses
Used in Textile Industry:Reactive Red 221 is used as a dye for blended fabric dyeing in a one-bath step. It is suitable for high-temperature dyeing of cotton fabrics, providing fast stains that are resistant to fading and staining. Additionally, it is used for dyeing polyester/nylon, nylon/cotton, and polyester/silk blended fabrics.
Standard:
The standard for Reactive Red 221 includes the following ratings for light fastness, oxygen bleaching, perspiration fastness, and soaping:
Light Fastness: 4
Oxygen Bleaching: 4-5
Perspiration Fastness: 4-5
Soaping: 4-5
Fading: 4
Stain: 4
Preparation
4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?and 2,4,6-Trichloro-1,3,5-triazine condensation, again with Nicotinic acid condensation, the 2-Aminobenzenesulfonic acid diazo, and condensation product matches, and then generate a product (2 Moore) and Benzene-1,4-diamine condensation.Standard

The CAS Registry Mumber 96726-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,7,2 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 96726-27:
(7*9)+(6*6)+(5*7)+(4*2)+(3*6)+(2*2)+(1*7)=171
171 % 10 = 1
So 96726-27-1 is a valid CAS Registry Number.
