6408-73-7 Usage
Uses
Used in Textile Industry:
Disodium 4,4'-[(1,4-diamino-9,10-dihydro-9,10-dioxo-2,3-anthrylene)bis(oxy)]bis[benzenesulphonate] is used as a dye for textiles due to its bright purple color and solubility in alcohol. It provides good light fastness, soaping, perspiration fastness, and fastness to oxygen bleaching and seawater, making it suitable for various textile applications.
Used in Color Fastness Testing:
Disodium 4,4'-[(1,4-diamino-9,10-dihydro-9,10-dioxo-2,3-anthrylene)bis(oxy)]bis[benzenesulphonate] is used in color fastness testing to evaluate the performance of dyes and textiles under various conditions, such as fading, staining, and resistance to different environmental factors. It helps in determining the ISO ratings for light fastness, soaping, perspiration fastness, oxygen bleaching, and fastness to seawater.
Preparation
1,4-Diamino-2,3-dichloroanthracene-9,10-dione and?phenol?condensation, and then stlfonation, and translated into sodium salt.
Standard
Light Fastness
Fading
Stain

Check Digit Verification of cas no
The CAS Registry Mumber 6408-73-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6408-73:
(6*6)+(5*4)+(4*0)+(3*8)+(2*7)+(1*3)=97
97 % 10 = 7
So 6408-73-7 is a valid CAS Registry Number.
