6226-90-0 Usage
Description
Solvent Red 31 is a dark red powder that is insoluble in water and slightly soluble in ethanol, producing a magenta color. It exhibits a purple color in concentrated sulfuric acid, which turns pink upon dilution. Its aqueous dye solution turns red when concentrated hydrochloric acid is added and brown when a thick sodium hydroxide solution is added. It has a stable melting point and is classified under the ISO standard.
Uses
Used in Plastic Industry:
Solvent Red 31 is used as a colorant for plastic materials to provide them with a vibrant red hue.
Used in Grease Industry:
Solvent Red 31 is used as a coloring agent in greases to enhance their appearance and make them easily distinguishable.
Used in Printing Ink Industry:
Solvent Red 31 is used as a pigment in printing inks to achieve a consistent and long-lasting red color in printed materials.
Used in Paint Industry:
Solvent Red 31 is used as a dye in paint formulations to impart a rich red color to various surfaces.
Properties:
Solvent Red 31 demonstrates good light fastness and heat resistance up to 120°C for 1 hour. However, it has poor solubility in water and shows poor to well solubility when mixed with sodium carbonate (5%) and hydrochloric acid (5%), respectively.
Preparation
4-(Phenyldiazenyl)benzenamine diazotization and 7-Hydroxynaphthalene-1,3,6-trisulfonic acid coupling, and then translate into dicyclohexyl amine salt.

Check Digit Verification of cas no
The CAS Registry Mumber 6226-90-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6226-90:
(6*6)+(5*2)+(4*2)+(3*6)+(2*9)+(1*0)=90
90 % 10 = 0
So 6226-90-0 is a valid CAS Registry Number.
