125830-49-1 Usage
Uses
Used in Textile Industry:
Reactive Red 250 is used as a dye for coloring fabrics. Its light fastness ensures that the color remains vibrant and resistant to fading when exposed to sunlight. The oxygen bleaching property allows the dye to withstand the bleaching process without losing its color intensity. The perspiration fastness ensures that the color does not fade when the fabric comes into contact with sweat. The soaping property allows the dye to be easily washed out during the dyeing process, reducing the risk of staining.
Reactive Red 250 is also used as a dye for various types of fabrics, including natural fibers like cotton, wool, and silk, as well as synthetic fibers like polyester and nylon. Its versatility and colorfastness make it a popular choice for a wide range of applications, from clothing and accessories to home textiles and decorative items.

Check Digit Verification of cas no
The CAS Registry Mumber 125830-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,8,3 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125830-49:
(8*1)+(7*2)+(6*5)+(5*8)+(4*3)+(3*0)+(2*4)+(1*9)=121
121 % 10 = 1
So 125830-49-1 is a valid CAS Registry Number.
