70210-20-7 Usage
Uses
Used in Textile Industry:
Reactive Red 24 is used as a dye for cotton or viscose fiber dissemination, roll dye, knot dyeing, and piled up dyeing. It is also used for direct dye printing on cotton or viscose fabric.
Standard:
Reactive Red 24 has a light fastness rating of 5-6 on the ISO scale, indicating its resistance to fading under direct sunlight. It has an oxygen bleaching rating of 4-5, which means it may fade when exposed to oxygen bleach. The perspiration fastness and soaping ratings are both 5, suggesting that the dye is resistant to fading when exposed to sweat or soap.
Preparation
4-Amino-5-hydroxynaphthalene-2,7-disulfonic acidand 2,4,6-Trichloro-1,3,5-triazine condensation, 2-Aminobenzenesulfonic acid diazo, coupled with condensation products, and then and N-methylbenzenamine condensation and salting-out.

Check Digit Verification of cas no
The CAS Registry Mumber 70210-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,1 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70210-20:
(7*7)+(6*0)+(5*2)+(4*1)+(3*0)+(2*2)+(1*0)=67
67 % 10 = 7
So 70210-20-7 is a valid CAS Registry Number.
