6247-28-5 Usage
Description
CI 11875, also known as a dye, is a chemical compound that exhibits various properties and characteristics. It is characterized by its deep green light brown to dark brown color. It is soluble in hot water, resulting in a yellow brown color, and slightly soluble in ethanol and acetone. When mixed with concentrated sulfuric acid, it produces a brown light orange to red color, with orange precipitation upon dilution. In concentrated nitric acid, it forms an orange solution, while it is almost insoluble in concentrated hydrochloric acid. When mixed with a dilute sodium hydroxide solution, it forms a red solution.
Uses
Used in Textile Industry:
CI 11875 is used as a dye for textiles, providing a range of colors from deep green light brown to dark brown. Its solubility in hot water and slight solubility in ethanol and acetone make it suitable for dyeing various types of fabrics.
Used in Color Fastness:
CI 11875 is used to improve the color fastness of textiles, as indicated by its ISO ratings. It has a rating of 4-5 for ironing and light fastness, 3-4 for fulling and perspiration fastness, and 2 for soaping fastness. These ratings suggest that the dye is relatively resistant to fading or color change under various conditions, such as exposure to light, heat, and moisture.
Used in Acid and Alkali Resistance:
CI 11875 is also used to enhance the acid and alkali resistance of textiles. It has an ISO rating of 4-5 for both water and alkali resistance, indicating that the dyed fabric is less likely to be damaged or discolored when exposed to acidic or alkaline substances.

Check Digit Verification of cas no
The CAS Registry Mumber 6247-28-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,4 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6247-28:
(6*6)+(5*2)+(4*4)+(3*7)+(2*2)+(1*8)=95
95 % 10 = 5
So 6247-28-5 is a valid CAS Registry Number.
