Uses
Used in Textile Industry:
Disodium 3,3'-[carbonylbis[imino(3-methoxy-4,1-phenylene)azo]]dibenzoate is used as a dye for cotton, viscose, silk, and rayon blended dyeing. It is suitable for dyeing these materials due to its solubility and color properties. However, it is not used for printing.
Used in Paper and Leather Industry:
Disodium 3,3'-[carbonylbis[imino(3-methoxy-4,1-phenylene)azo]]dibenzoate is also used for dyeing paper and leather, taking advantage of its solubility and color characteristics.
Standard:
The standard for disodium 3,3'-[carbonylbis[imino(3-methoxy-4,1-phenylene)azo]]dibenzoate includes the following properties:
Acid Resistance: 3
Alkali Resistance: 5
Light Fastness: 4
Soaping: 2
Water Fading: 2
Stain Fading: 2
These properties indicate the compound's resistance to various conditions, such as acid, alkali, and light exposure, as well as its performance in soaping and water fading, which are important factors in the dyeing process.
Preparation
3-Aminobenzoic acid?diazo, and (2-Methoxyphenylamino)methanesulfonic acid coupling, then the water with sulfonic acid base, and then to light gasification.

Check Digit Verification of cas no
The CAS Registry Mumber 6420-30-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6420-30:
(6*6)+(5*4)+(4*2)+(3*0)+(2*3)+(1*0)=70
70 % 10 = 0
So 6420-30-0 is a valid CAS Registry Number.
