Uses
Patent Blue A (CAS# 3486-30-4) is an organic acid dye used in textiles and cosmetics. Patent Blue A is a pollutant due to its water solubility and difficult removal process.
Preparation
4-Formylbenzene-1,3-disulfonic acid and N-benzyl-N-ethylbenzenamine (2 Moore) condensation and oxidation.
Flammability and Explosibility
Nonflammable
Properties and Applications
colourful green light blue. Blue powder. Soluble in water, but soluble in ethanol is blue. The strong sulfuric acid are olive green, yellow precipitation after diluted. A transparent green light blue aqueous solution at room temperature without gathered tendency, add sodium hydroxide subject to change after cooling,heated to boiling color from blue to violet precipitate. In dyeing copper and iron ions become dark green color. For heavy chromate salt not sensitive. For wool, silk and polyamide fiber fabric dyeing and printing, and can also be used in leather, paper, cosmetics, soap, biological and rubber color.

Check Digit Verification of cas no
The CAS Registry Mumber 3486-30-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,8 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3486-30:
(6*3)+(5*4)+(4*8)+(3*6)+(2*3)+(1*0)=94
94 % 10 = 4
So 3486-30-4 is a valid CAS Registry Number.
