Description
Reactive Yellow 3 is a synthetic organic pigment characterized by its bright yellow color and reactive properties, which allow it to form covalent bonds with various substrates. It is known for its colorfastness, lightfastness, and resistance to fading, making it a popular choice for various applications.
Uses
Used in Textile Industry:
Reactive Yellow 3 is used as a dye for coloring fabrics, particularly cotton and its blends. Its reactive nature enables it to form strong bonds with the cellulose fibers, resulting in vibrant, long-lasting colors that are resistant to washing and fading.
Used in Plastics Industry:
Reactive Yellow 3 is used as a pigment for colorizing plastics. Its ability to form covalent bonds with the polymer matrix ensures that the color remains stable and does not leach out over time. However, it is important to note that Reactive Yellow 3 can degrade under UV light, which may affect its performance in outdoor applications or in products exposed to sunlight.
Used in Paper Industry:
Reactive Yellow 3 is used as a pigment for coloring paper products. Its lightfastness and resistance to fading make it suitable for use in printing inks, ensuring that the printed colors remain vibrant and consistent over time.
Used in Cosmetics Industry:
Reactive Yellow 3 is used as a colorant in various cosmetic products, such as hair dyes, makeup, and nail polishes. Its stability and resistance to fading contribute to the long-lasting and vibrant colors in these products.
It is important to consider the potential degradation of Reactive Yellow 3 under UV light when selecting it for specific applications, as this may impact its performance and longevity in certain environments.

Check Digit Verification of cas no
The CAS Registry Mumber 6539-67-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,3 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6539-67:
(6*6)+(5*5)+(4*3)+(3*9)+(2*6)+(1*7)=119
119 % 10 = 9
So 6539-67-9 is a valid CAS Registry Number.
