Sulfones are flexible functional groups that can act as nucleophiles, electrophiles, or even radicals. Changing the reaction conditions can completely alter the reactivity of a sulfonyl group, and as a result, molecules bearing multiple sulfones are versatile building blocks.
Vinyl sulfone dyes are reactive dyes comprising a vinyl sulfone group as reactive group (a fiber-bonding site of the reactive dye, "reactive hook"). Due to the relatively high reactivity of the vinyl sulfone group with water (residual moisture, air humidity), it is present in many commercial products in a protected form.
Vinyl sulfone esters are primarily used in the manufacturing of dyes, including reactive dyes. The growth of various industries such as paper, textiles, wood, leather, etc., is a major driver of the reactive dye industry.
Vinyl sulphone-reactive dyes are very popular and are the class of dyes that are involved in a nucleophilic addition reaction with cellulose fibres. These dyes are known for their excellent efficiency and have strong exhaustion and fixation properties.
