10343-55-2 Usage
Description
Solvent Yellow 19 is a synthetic organic dye that appears as a yellow powder. It is insoluble in water but soluble in organic solvents such as ethanol, acetone, and chloroform. The dye exhibits heat resistance, fastness, and good alkali resistance, making it suitable for various applications.
Uses
Used in Resin Industry:
Solvent Yellow 19 is used as a coloring agent in the resin industry to impart a vibrant yellow color to the final product. Its heat resistance and fastness properties ensure that the color remains stable during the manufacturing process.
Used in Transparent Lacquer Industry:
In the transparent lacquer industry, Solvent Yellow 19 is utilized as a pigment to provide a bright yellow hue to the lacquer. Its good alkali resistance and light fastness contribute to the durability and long-lasting appearance of the lacquer.
Used in Aluminum Foil Industry:
Solvent Yellow 19 is employed as a coloring agent in the aluminum foil industry to add a yellow tint to the foil. Its heat resistance and stability make it an ideal choice for coloring aluminum foil, which is often used in packaging and other applications where heat exposure is common.
Standard:
Solvent Yellow 19 meets the ISO standard for quality and performance. It demonstrates well light fastness and heat resistance up to 170°C. However, it has poor water solubility and reacts with sodium carbonate (5%) and hydrochloric acid (5%) without any significant change in its properties. The melting point of Solvent Yellow 19 is stable, indicating its reliability in various industrial applications.
Preparation
3-Amino-2-hydroxy-5-nitrobenzenesulfonic acid diazotization, and 3-Oxo-N-phenylbutanamide?coupling, and then the aqueous solution with fluorinated common heating.

Check Digit Verification of cas no
The CAS Registry Mumber 10343-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,4 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10343-55:
(7*1)+(6*0)+(5*3)+(4*4)+(3*3)+(2*5)+(1*5)=62
62 % 10 = 2
So 10343-55-2 is a valid CAS Registry Number.
