12227-62-2 Usage
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.
Flammability and Explosibility
Notclassified
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.
