6483-77-8 Usage
Preparation
4-(4-Aminophenyl)benzenamine double nitriding, first coupled with 2-Hydroxybenzoic acid, and then and 4-Aminobenzene-1,3-disulfonic acid diazo, and Benzene-1,3-diamine coupled to a product matches.
Properties and Applications
brown. Brown powder. Soluble in water for yellow orange brown solution, soluble in ethanol, insoluble in other organic solvents. The strong sulfuric acid for violet black, diluted for brown. The dye solution to join thick and strong hydrochloric acid sodium hydroxide solution are generating orange brown precipitation. Cellulose fiber of dyeing, the dye devoured performance is good, temperature in 80 ℃, the largest affinity, discharge the gender is good, hard to sensitive. After dyeing with copper sulfate handling,can improve the dyeing fastness. Dyeing cotton and viscose for yellow brown.

Check Digit Verification of cas no
The CAS Registry Mumber 6483-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6483-77:
(6*6)+(5*4)+(4*8)+(3*3)+(2*7)+(1*7)=118
118 % 10 = 8
So 6483-77-8 is a valid CAS Registry Number.
