12227-62-2 Usage
Description
Aluminum, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex is a purple fine powder that is odorless and has blu-ray red properties. It is hardly soluble in water, oil, and most solvents, but can be dispersed, mixed with water, oil liquid, and solid powder. The product is made by adding a certain amount of strong HCL and diluting it with a certain volume of two potassium hydrogen sulfate solutions, with a maximum absorption wavelength of 520 + 2 nm.
Uses
Used in Oil Products:
Aluminum, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex is used as a colorant for oil products, where powder of solid and colloid water-soluble colorants are difficult to use. It provides effective shading for these items.
Used in Solid and Colloid Water-Soluble Colorants:
Aluminum, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex is used as a colorant for solid and colloid water-soluble colorants that are difficult to use. It offers effective shading for these items.
Used in Acid and Alkali Applications:
Aluminum, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex is used in acid and alkali applications, where it exhibits its use effect through the congress effect.
Preparation
4-Aminonaphthalene-1-sulfonic acid diazo, and 3-Hydroxynaphthalene-2,7-disulfonic acid coupling, and then into aluminum salt deposit color.

Check Digit Verification of cas no
The CAS Registry Mumber 12227-62-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12227-62:
(7*1)+(6*2)+(5*2)+(4*2)+(3*7)+(2*6)+(1*2)=72
72 % 10 = 2
So 12227-62-2 is a valid CAS Registry Number.
