For example, Reactive Blue RB also known as Remazol brilliant blue is an anthraquinone based vinylsulphone dye, which is very resistant to chemical oxidation due to its anthraquinone structure being stabilized by resonance [6]. The term anthraquinone, however, almost invariably refers to one specific isomer, 9,anthraquinone IUPAC: The reaction mechanism may involve single electron transfer SET.

Archived from the original on Anthraquinone glycosides, tannin, and salicylic acid in the product react with the proteins of the epithelial cells in the mucous membranes and lead to a stronger adhesion of the mucosa and a reduction in the permeability of cells.
