Sulfoxide (R₂SO) is any of various organic sulfur compounds having the group -SO (sulfinyl group) whereas sulfone (RSOOR) with the group -SO₂ (sulfonyl group). They are derived from oxidation of sulfides ((R-S-R). Thioethers (organic sulfides) can be oxidized either to oxidation state -1 disulfides (R-S-S-R) or to oxidation state 0 sulfoxides (R-S(=O)-R) which can be further oxidized to the corresponding oxidation state +2 sulfones (R-S(=O)₂-R) depending on the structure of the thioether. They are widely used as solvent of both extraction and reaction as well as intermediates for the synthesis of textile chemicals and pharmaceuticals and agrochemicals.

Dimethyl Sulfone is an effective extraction solvent and solvent improver for the separation of aromatic compounds (benzene, toluene and xylenes) from aliphatic hydrocarbons, and for fractionation of unsaturated components (olefins and alkynes) from saturated feedstock. It is used as a thermally stable medium for carrying out chemical reactions in polymerization process as well as to make pharmaceuticals, agrochemicals, paint and coating materials and biocides. Dimethyl Sulfone is known that it is involved in hair and nail growth in the body.

The common examples of sulfone compounds are dapsone (4,4'-sulfonylbisbenzenamine) and its derivative. Dapsone (4,4'-sulfonylbisbenzenamine) is a parent compound in preparing sulfonamide antibacterial agents such as acedapsone, acetosulfone, glucosulfone, sulfoxone and solapsone. Dapsone and its derivatives have bacteriostatic activity against a broad spectrum of gram-negative and gram-positive organisms. Dapsone is a primary treatment for Dermatitis herpetiformis and in the treatment of leprosy (Mycobacterium leprae infections) leads to apparent improvementas. It is used in the prophylaxis of falciparum malaria. It is a white crystalline powder; melting point 175 - 180C; insoluble in water and vegetable oils. Dapsone is also widely used in polymer industry as a cross linkage agent in manufacturing polysulfone amide engineering plastics. Sulfone-containing engineering plastics are thermally stable and have high resistance property to acids and alkalis. Tazobactam is a penicillanic acid sulfone derivative which acts as a beta-lactamase inhibitor similar to sulbactam. Tazobactam is used in combination with piperacillin to widen the spectrum of activity. Sulfone class compounds which have a sulfonyl group attached to two carbon atoms are active as an antibiotic.
