110735-25-6 Usage
Preparation
3,3′-Dimethoxylbenzidine double nitriding, first and 4-Hydroxynaphthalene-1-sulfonic acid conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling.
Properties and Applications
red light blue. Blue-black powder. Soluble in water for blue purple or purple solution, and adequate soluble in ethanol for red light purple. The strong sulfuric acid in blue or green for Tracy blu-ray, diluted for purple. The dye solution to join strong hydrochloric acid for purple, have precipitation; Add thick red or purple sodium hydroxide solution for red wine. Cellulose fiber of dyeing, dye devoured rate is very good, temperature in 100 ℃, the largest affinity, discharge the gender is good. When dyeing with copper sulphate treatment can improve a resistance fastness, with?formaldehyde treatment can improve washing fastness. Mainly used?for cotton, linen, rayon and other cellulose fibers, rayon / brocade fabric dyeing, leather and paper pulp can also be used for coloring.

Check Digit Verification of cas no
The CAS Registry Mumber 110735-25-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,7,3 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 110735-25:
(8*1)+(7*1)+(6*0)+(5*7)+(4*3)+(3*5)+(2*2)+(1*5)=86
86 % 10 = 6
So 110735-25-6 is a valid CAS Registry Number.
