C.I. Reactive Yellow 7, also known as Reactive Yellow M-4R, is a synthetic azo dye characterized by its water solubility and high reactivity due to the presence of azo and sulfonate groups in its chemical structure. It is widely recognized for its ability to form a chemical bond with the fibers of the fabric, providing a more permanent and colorfast dyeing effect, particularly in the textile industry.

12226-46-9 Usage
Uses
Used in Textile Industry:C.I. Reactive Yellow 7 is used as a dyeing agent for various natural fibers such as cotton, silk, and wool. Its application is favored for its ability to create a permanent and colorfast dyeing effect, which is crucial for the production of high-quality textiles.
The dye's reactivity with the textile substrate is attributed to its chemical structure, which includes azo and sulfonate groups. This allows it to form a strong bond with the fibers, ensuring the color's durability and resistance to fading over time.
Check Digit Verification of cas no
The CAS Registry Mumber 12226-46-9 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 6 respectively; the second part has 2 digits, 4 and 6 respectively.Calculate Digit Verification of CAS Registry Number 12226-46:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*4)+(1*6)=69
69 % 10 = 9
So 12226-46-9 is a valid CAS Registry Number.
