Description
Mordant Brown 33 is a yellow-brown powder that is soluble in water and ethanol, slightly soluble in acetone, and insoluble in other organic solvents. It is a dye that changes color when exposed to different chemicals, such as concentrated sulfuric acid, concentrated nitric acid, hydrochloric acid, and sodium hydroxide solution. It is primarily used for dyeing wool fabrics, particularly for carpets, wool tops, and other wool products, as well as silk, nylon, and leather.
Uses
Used in Textile Industry:
Mordant Brown 33 is used as a dye for wool fabrics, particularly for carpet, wool, and wool top dyeing, due to its ability to produce a vibrant color and its compatibility with these materials.
Used in Silk, Nylon, and Leather Dyeing:
Mordant Brown 33 is also used as a dye for silk, nylon, and leather, as it can provide a consistent and long-lasting color to these materials.
Used in Blended Fiber Dyeing:
Mordant Brown 33 can be used for dyeing wool and various fiber blends in a single bath, making it a versatile dye for different types of fabrics.
Used in Direct Printing on Wool and Silk Fabrics:
Mordant Brown 33 can be used for direct printing on wool and silk fabrics after acetic acid chromium pretreatment, allowing for more intricate and detailed designs.

Check Digit Verification of cas no
The CAS Registry Mumber 3618-62-0 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 3618-62:
(6*3)+(5*6)+(4*1)+(3*8)+(2*6)+(1*2)=90
90 % 10 = 0
So 3618-62-0 is a valid CAS Registry Number.
