It is characterized by its solubility in various solvents such as acetone, ethanol, and benzene, and its insolubility in special solvents like tao. This dye is available as a navy blue powder and is suitable for dyeing and printing on a range of synthetic fibers.
Uses
Used in Textile Industry:
Disperse Blue 3 is used as a textile dye for coloring synthetic fibers such as nylon, acrylic, polyester, and acetate. It is particularly used as a stocking dye, providing vibrant and long-lasting color to these materials.
Used in Colloidal Dye Form:
In addition to its use as a textile dye, Disperse Blue 3 is also available as a colloidal dye, which allows for its application in various industries where coloration is required.
Used in Polyamide Dyeing and Printing:
Disperse Blue 3 is used as a dye for polyamide fibers, providing excellent colorfastness properties. It offers good ironing fastness, light fastness, perspiration fastness, and washing fastness, with ratings ranging from 3 to 5 according to ISO and AATCC standards.
Used in Acrylic Dyeing and Printing:
This dye is also suitable for dyeing and printing on acrylic fibers, offering a range of colorfastness properties that make it a versatile choice for the textile industry.
Although Disperse Blue 3 can be used for dyeing polyester, its performance in terms of rubbing fastness and sunlight resistance is not as good as on other synthetic fibers. However, it can still be used for thermoplastic coloration purposes.

Check Digit Verification of cas no
The CAS Registry Mumber 2475-46-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,7 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2475-46:
(6*2)+(5*4)+(4*7)+(3*5)+(2*4)+(1*6)=89
89 % 10 = 9
So 2475-46-9 is a valid CAS Registry Number.
