5850-64-6 Usage
Description
ACID RED 60, also known as an organic azo dye, is a synthetic compound characterized by its vibrant red color. It is known for its solubility in water, where it appears red, and its slight solubility in ethanol, where it takes on a pink hue. The dye's color can be altered by the presence of strong sulfuric acid, turning it blue, and by the addition of strong hydrochloric acid or sodium hydroxide, which results in red and purple hues, respectively. ACID RED 60 is recognized for its light fastness, soaping fastness, perspiration fastness, and resistance to fading and staining in various conditions, including exposure to oxygen bleaching and seawater.
Uses
Used in Textile Industry:
ACID RED 60 is used as a colorant for dyeing fabrics, providing a vibrant red hue that is resistant to fading and staining under various conditions. Its light fastness, soaping fastness, and perspiration fastness make it a suitable choice for textiles that are frequently exposed to light, water, and sweat.
Used in Ink Industry:
ACID RED 60 is also used as a pigment in the production of ink, particularly for inkjet printers. Its solubility in water and ability to produce a strong red color make it an ideal choice for creating high-quality, long-lasting prints.

Check Digit Verification of cas no
The CAS Registry Mumber 5850-64-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5850-64:
(6*5)+(5*8)+(4*5)+(3*0)+(2*6)+(1*4)=106
106 % 10 = 6
So 5850-64-6 is a valid CAS Registry Number.
