6359-50-8 Usage
Description
Basic Yellow 21 is a bright yellow powder that exhibits colorful green light yellow color. It is soluble in water and maintains its color light unchanged even at high temperatures of 120°C during dyeing. The dye's color shade remains unchanged in the presence of copper ions, but it experiences a slight change in color and lustre when encountering iron ions. It has a compatibility value of 2.5 and an f value of 0.29, with a solubility of 40 g/L, which is minimally affected by temperature.
Uses
Used in Acrylic Dyeing Industry:
Basic Yellow 21 is used as a dye for acrylic fibers due to its bright color, high solubility, and minimal temperature effect on solubility. It provides good light fastness, perspiration fastness, ironing fastness, and soaping properties, making it suitable for dyeing acrylic materials.
Used in Direct Acrylic Fiber Printing:
Basic Yellow 21 is also used for direct printing on acrylic fibers, offering the same benefits as in dyeing, such as bright color, high solubility, and good fastness properties.

Check Digit Verification of cas no
The CAS Registry Mumber 6359-50-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6359-50:
(6*6)+(5*3)+(4*5)+(3*9)+(2*5)+(1*0)=108
108 % 10 = 8
So 6359-50-8 is a valid CAS Registry Number.
