Reactive red 66

CAS: 70210-39-8

Reactive red 66 is a reactive dye that is used for wastewater treatment. The high resistance to hydrochloric acid, photo-oxidation, and protease activity make it an ideal candidate for this application. Reactive red 66 has been shown to have the ability to react with proteins and other compounds in the water to form covalent bonds. These bonds are then broken down by reductive mechanisms such as photocatalytic activity, which results in the formation of radicals. Functional groups on the molecule are responsible for its color, while transfer mechanisms between molecules allow it to be soluble in water at low concentrations.
