Description
Mordant Red 7 is a blue light red powder that is soluble in water, resulting in a yellow to brown light red color. It is slightly soluble in ethanol and acetone but insoluble in other organic solvents. When dissolved in concentrated sulfuric acid, it appears magenta, turning orange upon dilution. In concentrated nitric acid, it forms an orange solution. Its dye aqueous solution, when combined with 10% sulfuric acid, results in a red-orange color. It also exhibits a cheery red or bright red color when in contact with strong caustic substances.
Uses
Used in Textile Industry:
Mordant Red 7 is used as a dye for wool fabric, providing a vibrant and long-lasting color. It is also used for dyeing scattered hair, tops, blankets, and other woolen fabrics. Additionally, it can be used to dye silk, polyamide fiber, and their blended fabrics. Mordant Red 7 is suitable for direct printing on wool and silk fabrics, offering a wide range of applications in the textile industry.

Check Digit Verification of cas no
The CAS Registry Mumber 3618-63-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,1 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3618-63:
(6*3)+(5*6)+(4*1)+(3*8)+(2*6)+(1*3)=91
91 % 10 = 1
So 3618-63-1 is a valid CAS Registry Number.
