Description
Trisodium 4-hydroxy-5-[[5-sulphonato-4-[(p-tolyl)amino]naphthyl]azo]naphthalene-2,7-disulphonate is a water-soluble azo dye that exhibits red light blue color. It is soluble in water and ethanol, but insoluble in other organic solvents. The dye undergoes color changes in the presence of strong acids, turning blue-black in concentrated sulfuric acid and dark yellow in nitric acid.
Uses
Used in Textile Industry:
Trisodium 4-hydroxy-5-[[5-sulphonato-4-[(p-tolyl)amino]naphthyl]azo]naphthalene-2,7-disulphonate is used as a dye for coloring textiles. It is valued for its light fastness, soaping fastness, perspiration fastness, and resistance to oxygen bleaching and seawater.
Used in Color Measurement:
The dye is also used in color measurement applications, where its color properties and fastness to various conditions are assessed using ISO and AATCC standards. This helps in determining the quality and performance of the dye in different environments.

Check Digit Verification of cas no
The CAS Registry Mumber 10359-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,5 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10359-95:
(7*1)+(6*0)+(5*3)+(4*5)+(3*9)+(2*9)+(1*5)=92
92 % 10 = 2
So 10359-95-2 is a valid CAS Registry Number.
