CAS 12236-86-1
:Reactive Blue 21
Description:
Reactive Blue 21 is a synthetic dye belonging to the class of reactive dyes, primarily used in textile applications for dyeing cellulose fibers such as cotton. It is characterized by its vivid blue color and high reactivity, which allows it to form covalent bonds with the hydroxyl groups in cellulose, resulting in strong and durable coloration. The dye is water-soluble, making it suitable for various dyeing processes, including exhaust and continuous dyeing methods. Reactive Blue 21 is known for its excellent lightfastness and washfastness properties, which contribute to the longevity of the dyed fabric. However, like many synthetic dyes, it may pose environmental concerns due to its potential toxicity and the need for proper wastewater treatment during the dyeing process. Safety data sheets indicate that appropriate handling and protective measures should be taken to minimize exposure during its use. Overall, Reactive Blue 21 is a valuable compound in the textile industry, offering both aesthetic appeal and functional performance.

Reactive blue 21
CAS:<p>Reactive Blue 21 is a kinetic, high-salt and reactive dye that is used as an analytical indicator. It has been shown to be useful in wastewater treatment, where it has been used to measure the adsorption of cationic surfactants on activated sludge. Reactive Blue 21 is also used as a feedstock for the production of polyclonal antibodies. The FTIR spectrum of this dye shows that it contains a pyrazole ring with an absorption band at 2,600 cm-1.</p>Purity:Min. 95%Color and Shape:Powder
