6222-44-2 Usage
Description
Mordant Green 28 is a synthetic dye characterized by its dark blue to light green color. It exhibits various color changes when interacting with different chemicals, such as turning red in concentrated sulfuric acid and plum red upon dilution. In a 10% sodium hydroxide solution, it appears as a red-light purple color. When its aqueous dye solution is mixed with hydrochloric acid, it forms a brown-light red precipitate.
Uses
Used in Textile Industry:
Mordant Green 28 is used as a dye for coloring fabrics, providing a vibrant dark blue to light green hue. Its ability to produce different shades when interacting with various chemicals makes it a versatile choice for the textile industry.
Used in Dye Testing and Quality Control:
Mordant Green 28 is utilized in testing the fastness and performance of dyes under various conditions, such as light, water, alkali, and acid. The standard ISO ratings for its fastness properties are as follows:
Ironing Fastness: 5
Light Fastness: 3-4
Fulling: 4
Perspiration Fastness: 5
Soaping: 4-5
These ratings indicate the dye's resistance to fading or color change under different environmental and treatment conditions, making it a valuable tool for ensuring the quality and durability of dyed textiles.

Check Digit Verification of cas no
The CAS Registry Mumber 6222-44-2 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 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6222-44:
(6*6)+(5*2)+(4*2)+(3*2)+(2*4)+(1*4)=72
72 % 10 = 2
So 6222-44-2 is a valid CAS Registry Number.
