12226-20-9 Usage

Description

C.I. Reactive Red 43 is a synthetic dye characterized by its yellow light red color. It exhibits good solubility in water, with a water solubility of 159 g/L at 60°C. This dye is known for its light fastness, oxygen bleaching resistance, and perspiration fastness, making it suitable for various applications in the textile industry.

Uses

Used in Textile Industry:
C.I. Reactive Red 43 is used as a dye for coloring fabrics. Its light fastness ensures that the color remains vibrant and resistant to fading under exposure to sunlight. The oxygen bleaching resistance helps maintain the color's integrity during the bleaching process, while the perspiration fastness ensures that the color does not fade when the fabric comes into contact with sweat.
C.I. Reactive Red 43 is also used for staining and fading applications in the textile industry. Its ability to produce a brilliant color even after soaping at high temperatures (95°C) makes it a preferred choice for染色 and fading processes.

Preparation

2,4,6-Trichloro-1,3,5-triazine and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid condensation, 2-Amino-5-methoxybenzenesulfonic acid diazo, and condensation products coupled, again with 3-Aminobenzenesulfonic acid condensation.

Check Digit Verification of cas no

The CAS Registry Mumber 12226-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12226-20:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*2)+(1*0)=59
59 % 10 = 9
So 12226-20-9 is a valid CAS Registry Number.
