2,7-Naphthalenedisulfonic acid, 4-amino-5-hydroxy-, diazotized, coupled with diazotized 4-nitro-1,3-benzenediamine and resorcinol, potassium sodium salts is a complex chemical mixture that is primarily used in the production of dyes and pigments. This mixture involves the diazotization of 4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid and 4-nitro-1,3-benzenediamine, followed by coupling with resorcinol. The potassium sodium salts in the mixture contribute to the stability and compatibility of the resulting diazo dye with various substrates.
Used in Textile Industry:
2,7-Naphthalenedisulfonic acid, 4-amino-5-hydroxy-, diazotized, coupled with diazotized 4-nitro-1,3-benzenediamine and resorcinol, potassium sodium salts is used as a dyeing agent for fabrics. The reason for its use is the creation of bright and intense colors on textiles, which are essential for producing visually appealing and long-lasting garments and other textile products.
Used in Inks and Colorants:
In addition to the textile industry, 2,7-Naphthalenedisulfonic acid, 4-amino-5-hydroxy-, diazotized, coupled with diazotized 4-nitro-1,3-benzenediamine and resorcinol, potassium sodium salts is also used in the production of inks and colorants. The application reason is the same as in the textile industry, where the vibrant and stable colors provided by this chemical mixture are crucial for creating high-quality inks and colorants for various applications.

Check Digit Verification of cas no

The CAS Registry Mumber 90432-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,3 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90432-08:
(7*9)+(6*0)+(5*4)+(4*3)+(3*2)+(2*0)+(1*8)=109
109 % 10 = 9
So 90432-08-9 is a valid CAS Registry Number.
