Reactive Red 35, also known as C.I. Reactive Red 35, is a synthetic azo dye characterized by its vibrant color and strong colorfastness. It is commonly utilized in the textile industry for dyeing various natural fibers such as cotton, wool, and silk. As a reactive dye, it forms covalent bonds with the fibers, ensuring the durability and intensity of the color. The chemical structure of Reactive Red 35 comprises aromatic rings and azo groups, which contribute to its striking appearance. However, its use has raised concerns due to potential environmental and health risks, including the release of toxic chemicals during production and use, as well as the possibility of causing skin irritation and allergic reactions in some individuals. Consequently, its application is regulated in certain countries, and the search for more sustainable and safer dyeing alternatives is ongoing.

12226-12-9 Usage
Uses
Used in Textile Industry:Reactive Red 35 is used as a dyeing agent for natural fibers such as cotton, wool, and silk. It is favored for its ability to form covalent bonds with the fibers, resulting in strong and colorfast dyes that are resistant to fading and washing.
Used in Environmental and Health Regulations:
Due to the potential environmental and health risks associated with Reactive Red 35, it is subject to regulations in some countries. These regulations aim to minimize the release of toxic chemicals during production and use, as well as to reduce the risk of skin irritation and allergic reactions in individuals who come into contact with the dye.
Used in Research and Development of Alternative Dyes:
The search for more sustainable and safer dyeing processes has led to the exploration of alternative dyes to Reactive Red 35. Researchers and textile manufacturers are actively involved in the development of eco-friendly dyes that can provide similar colorfastness and vibrancy without the associated risks.
Check Digit Verification of cas no
The CAS Registry Mumber 12226-12-9 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, 1 and 2 respectively.Calculate Digit Verification of CAS Registry Number 12226-12:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*1)+(1*2)=59
59 % 10 = 9
So 12226-12-9 is a valid CAS Registry Number.
