2429-79-0 Usage
Uses
Used in Textile Industry:
Disodium 5-[[4'-[(1-amino-4-sulphonato-2-naphthyl)azo][1,1'-biphenyl]-4-yl]azo]salicylate is used as a dye for cotton due to its ability to produce a red light orange color. It is also used for paper shading, providing a similar color effect.
Used in Paper Industry:
In the paper industry, disodium 5-[[4'-[(1-amino-4-sulphonato-2-naphthyl)azo][1,1'-biphenyl]-4-yl]azo]salicylate is used as a shading agent to impart a red light orange color to paper products.
Standard:
The dye exhibits the following properties according to the provided standards:
Acid Resistance: ISO 1-2, AATCC 1
Alkali Resistance: ISO 3, AATCC 2
Light Fastness: ISO 1, AATCC 2-3
Soaping: ISO 2, AATCC 1
Water Fading: ISO 2, AATCC 2
Stain Fading: Not provided
Stain: Not provided
These properties indicate the dye's performance and resistance to various conditions, making it suitable for use in the textile and paper industries.
Preparation
4-(4-Aminophenyl)benzenamine double nitriding, first with 2-Hydroxybenzoic acid coupling, again with 4-Aminonaphthalene-1-sulfonic acid matches. In some brands, Part of the 2-Hydroxybenzoic acid?can be 2-Hydroxy-3-methylbenzoic acid , and can be used other amino acid naphthalene replaced the 4-Aminonaphthalene-1-sulfonic acid.

Check Digit Verification of cas no
The CAS Registry Mumber 2429-79-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,2 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2429-79:
(6*2)+(5*4)+(4*2)+(3*9)+(2*7)+(1*9)=90
90 % 10 = 0
So 2429-79-0 is a valid CAS Registry Number.
