3441-14-3 Usage
Preparation
aniline and N-(4-aminophenyl)acetamide diazo respectively, and N,N’-bis(4-hydroxy-2-sulfonaphthalene-7-yl)urea coupling.
Hazard
Low toxicity by ingestion.
Properties and Applications
red. Purple powder. Soluble in water for colourful red, solubility of 30 g/L (80 ° C), soluble in ethanol for orange, insoluble in acetone. The strong sulfuric acid was great red to product red, diluted light orange for palm. The dye solution to generate strong hydrochloric acid wine red precipitate; Add 10% sulfuric acid into a light blue; Add thick sodium hydroxide solution for red orange; Add 10% sodium carbonate (no change solution. Cellulose fiber of dyeing, dye devoured rate is very good, in the 80 ~ 100 ℃, affinity is the largest. Resistant to acid is very good. Copper ions in dyeing color shade darker; Iron ion in the same light. Mainly used in viscose etc of cellulose fiber dyeing, also can be used for silk, wool, paper and pulp dyeing, also can be used in the manufacture color which have pigment.

Check Digit Verification of cas no
The CAS Registry Mumber 3441-14-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3441-14:
(6*3)+(5*4)+(4*4)+(3*1)+(2*1)+(1*4)=63
63 % 10 = 3
So 3441-14-3 is a valid CAS Registry Number.
