Description
Disperse red 126 is a synthetic azo dye that is characterized by its red color. It is commonly used in the textile industry for dyeing polyester and blended fabrics.Uses
Used in Textile Industry:Disperse red 126 is used as a dye for polyester and blended fabrics due to its excellent colorfastness properties. It exhibits good ironing fastness, light fastness, perspiration fastness, and washing fastness, making it a popular choice for various textile applications.
The standard for the colorfastness properties of Disperse red 126 is as follows:
Ironing Fastness: AATCC 4-5
Light Fastness: AATCC 5
Perspiration Fastness: AATCC 5
Washing Fastness: AATCC 5
These properties ensure that the color of the fabric remains vibrant and resistant to fading and staining, even under various conditions.

The CAS Registry Mumber 12236-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 12236-21:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*2)+(1*1)=64
64 % 10 = 4
So 12236-21-4 is a valid CAS Registry Number.
