(2-Hydroxyethyl) dimethylsulfoxonium chloride is an organic compound with the formula [HOCH₂CH₂S(O)(CH₃)₂]⁺Cl⁻. It is a sulfonium ion with a chloride counterion. The cation has been isolated from sea chervils and sea sponges. It causes the Dogger Bank itch.^[1]

Properties

(2-Hydroxyethyl) dimethylsulfoxonium chloride is colourless. It dissolves in dioxane, methanol, chloroform or water.^[2]

(2-Hydroxyethyl) dimethylsulfoxonium chloride is a salt, with a sulfur atom having a positive charge. Attached to the sulfur are two methyl groups, and oxygen atom, and an ethoxy group attached at the number 2 carbon. Its structure has been confirmed by X-ray crystallographys.^[2]

Natural occurrence

(2-Hydroxyethyl) dimethylsulfoxonium has been discovered so far in invertebrate animals in the genus Alcyonidium and a single species of sea sponge.^[3]
