2586-57-4 Usage
Description
CHLORAZOL BLUE RW is a blue-colored dye that is soluble in water, soluble fiber elements, and insoluble in organic solvents. It exhibits various color changes when exposed to different chemical agents, such as green light blue in strong sulfuric acid, purple precipitation after dilution, and palm gray solution in nitric acid. The dye solution also shows a blue-ray red color when mixed with rare hydrochloric acid and turns purple upon the addition of sodium hydroxide.
Uses
Used in Textile Industry:
CHLORAZOL BLUE RW is used as a dye for textiles, providing colorfastness and resistance to various conditions such as acid, alkali, light, soaping, water fading, and stain fading. It has a standard rating of 4-5 for acid and alkali resistance, 1 for light fastness, 1-2 for soaping, and 1-2 for water fading and stain fading according to ISO standards. In AATCC standards, it has a rating of 5 for acid and alkali resistance, 1-2 for light fastness, 3-4 for soaping, and 2-3 for water fading and stain fading.
Used in Analytical Chemistry:
CHLORAZOL BLUE RW can be used as an indicator in analytical chemistry due to its color-changing properties in the presence of different chemical agents. This makes it useful for detecting the presence of specific ions or pH levels in a solution.
Used in Research and Development:

Check Digit Verification of cas no
The CAS Registry Mumber 2586-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2586-57:
(6*2)+(5*5)+(4*8)+(3*6)+(2*5)+(1*7)=104
104 % 10 = 4
So 2586-57-4 is a valid CAS Registry Number.
