1324-53-4 Usage
Description
Acid Blue 138 is a blue powder that is soluble in water. It exhibits strong properties when combined with sulfuric acid, producing a green light blue color. The color changes to a lighter green when it comes into contact with copper ions and turns dark green when it encounters chromium ions. Acid Blue 138 is primarily used in the dyeing and printing industry, specifically for silk, wool, and polyamide fibers.
Uses
Used in Silk Printing and Dyeing Industry:
Acid Blue 138 is used as a dye for silk, providing a vibrant blue color that is fast and resistant to various conditions. It is favored for its ability to produce a consistent and long-lasting color.
Used in Wool Dyeing Industry:
Acid Blue 138 is used as a dye for wool, offering a strong and stable color that is resistant to fading and staining. Its light fastness and resistance to oxygen bleaching make it a popular choice for this application.
Used in Polyamide Fiber Dyeing Industry:
Acid Blue 138 is used as a dye for polyamide fibers, providing a deep and long-lasting blue color. Its fastness to seawater and resistance to fading and staining make it an ideal choice for this application.

Check Digit Verification of cas no
The CAS Registry Mumber 1324-53-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1324-53:
(6*1)+(5*3)+(4*2)+(3*4)+(2*5)+(1*3)=54
54 % 10 = 4
So 1324-53-4 is a valid CAS Registry Number.
