Reactive Blue 221, also known as C.I. 61200 or Remazol Blue, is a water-soluble reactive dye that is commonly used in the textile industry for dyeing cellulose-based fibers such as cotton. It is an azo dye, which means it contains nitrogen-nitrogen double bonds, and is known for its vibrant blue color. Reactive Blue 221 forms a covalent bond with cellulose fibers, resulting in excellent colorfastness and wash fastness.

89933-65-3 Usage
Uses
Used in Textile Industry:Reactive Blue 221 is used as a dye for cellulose-based fibers such as cotton, providing a vibrant blue color to textiles. It is particularly popular in the production of denim and other blue-colored fabrics.
Used in Denim Production:
Reactive Blue 221 is used as a dye in the production of denim, giving it the characteristic blue color. The dye's ability to form a covalent bond with cellulose fibers ensures excellent colorfastness and wash fastness, making it a preferred choice for denim manufacturing.
However, it is important to note that some azo dyes, including Reactive Blue 221, have been found to be toxic to aquatic organisms and may cause skin irritation in humans. This has led to concerns about their environmental and health impacts, and efforts are being made to develop safer alternatives for textile dyeing.
Check Digit Verification of cas no
The CAS Registry Mumber 89933-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,3 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 89933-65:
(7*8)+(6*9)+(5*9)+(4*3)+(3*3)+(2*6)+(1*5)=193
193 % 10 = 3
So 89933-65-3 is a valid CAS Registry Number.
