12221-63-5 Usage
Uses
Used in Textile Industry:
3-(3-amino-3-oxopropyl)-2-[[1-methyl-2-(p-tolyl)-1H-indol-3-yl]azo]benzothiazolium chloride is used as an acrylic dye for coloring acrylic fibers, wool, and other textile materials. Its strong red color and compatibility with other dyes make it suitable for dyeing and printing applications.
Used in Dye Compatibility:
With a compatibility value of 2.5 and an f value of 0.18, 3-(3-amino-3-oxopropyl)-2-[[1-methyl-2-(p-tolyl)-1H-indol-3-yl]azo]benzothiazolium chloride can be effectively mixed with other dyes to achieve desired color combinations and shades in textile dyeing processes.
Standard:
The dye exhibits good light fastness, perspiration fastness, ironing fastness, and soaping properties, making it suitable for various textile applications. According to the AATCC standards, it has ratings of 7 for light fastness, and 5 for perspiration, ironing, and soaping fastness, as well as for fading and staining resistance.
Preparation
2-Amino-3-(2-carbamoylethyl)benzothiazolium chloride diazo, and 1-Methyl-2-p-tolyl-1H-indole?coupled with acrylamide of quaternary ammonium salt.

Check Digit Verification of cas no
The CAS Registry Mumber 12221-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 12221-63:
(7*1)+(6*2)+(5*2)+(4*2)+(3*1)+(2*6)+(1*3)=55
55 % 10 = 5
So 12221-63-5 is a valid CAS Registry Number.
