Selenium disulfide, also known as selenium sulfide, is a chemical compound and medication used to treat seborrheic dermatitis, dandruff, and pityriasis versicolor. [ 1 ] [ 2 ] It is applied to the affected area as a lotion or shampoo. [ 3 ]
Selenium disulfide consists of 8-membered rings. It has an approximate composition of SeS 2, with individual rings varying in composition, such as Se 4 S 4 and Se 2 S 6. Selenium disulfide has been used in shampoo as an antidandruff agent, an inhibitor in polymer chemistry, a glass dye, and a reducing agent in fireworks. [24]

Cadmium red pigment. Some inorganic selenide sulfide compounds are also known. Simplest is the material selenium sulfide, which has medicinal properties.It adopt the diverse structures of elemental sulfur but with some S atoms replaced by Se.
Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 3 ...
Selenium is, however, an essential mineral element for animal (including human) nutrition and selenium deficiencies are known to occur when food or animal feed is grown on selenium-deficient soils. The use of inorganic selenium fertilizers can increase selenium concentrations in edible crops and animal diets thereby improving animal health. [31]
A disulfide ensemble is a grouping of all disulfide species with the same number of disulfide bonds, and is usually denoted as the 1S ensemble, the 2S ensemble, etc. for disulfide species having one, two, etc. disulfide bonds. Thus, the (26–84) disulfide species belongs to the 1S ensemble, whereas the (26–84, 58–110) species belongs to ...
Methyl methanethiosulfinate can also disproportionate to a 1:1 mixture of dimethyl disulfide and methyl methanethiosulfonate (CH 3 SO 2 SCH 3) and rearrange via a Pummerer rearrangement to CH 3 S(O)CH 2 SSCH 3. [20] [21] An unusual three-membered ring thiosulfinate (a dithiirane 1-oxide) has been prepared through rearrangement of a 1,3 ...
