2429-75-6 Usage
Preparation
4-(4-Aminophenyl)benzenamine double nitriding, in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid (2 Moore) coupled.
Properties and Applications
purple. Deep smoked uniform powder. Soluble in water for violet black, soluble in ethanol for product red. In the strong sulfuric acid as dark blue, diluted into dark purple. The dye solution to join strong hydrochloric acid for Red sauce or violet black, precipitation; Add thick sodium hydroxide solution for violet black, precipitation. Cellulose fiber of dyeing, the dye devoured the gender is good, in the 80 ~ 100 ℃ maximum when affinity. Hard to more sensitive. Mainly used for cotton, cellulose fiber fabrics such as glue of dyeing, also can be used for paper dyeing.

Check Digit Verification of cas no
The CAS Registry Mumber 2429-75-6 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 2429-75:
(6*2)+(5*4)+(4*2)+(3*9)+(2*7)+(1*5)=86
86 % 10 = 6
So 2429-75-6 is a valid CAS Registry Number.
