Preparation
4-(4-Aminophenyl)benzenamine double nitriding,3-Aminonaphthalene-2,7-disulfonic acid and phenol coupling, and then in the sodium hydroxide solution heat and pressure, with monomer (VCM) ethyl change.Properties and Applications
bright orange. Moderate soluble in water and ethanol for gold orange, soluble in soluble fiber element, insoluble in other organic solvents. In the dark for the strong sulfuric acid, diluted light yellow for subtle stitching, precipitation; In nitric acid solution for orange. The dye solution to join strong hydrochloric acid have yellow olive brown precipitation; Add thick sodium hydroxide solution for gold orange, precipitation. Used for wool, silk and polyamide fiber dyeing, wool dyeing in neutral or weak acid bath.

StainCheck Digit Verification of cas no
The CAS Registry Mumber 6528-39-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,2 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.Calculate Digit Verification of CAS Registry Number 6528-39:
(6*6)+(5*5)+(4*2)+(3*8)+(2*3)+(1*9)=108
108 % 10 = 8
So 6528-39-8 is a valid CAS Registry Number.
