thimerosal

organic compound used as an antiseptic for the skin and mucous membranes, sometimes marketed under the trade name Merthiolate. It is related to merbromin (Mercurochrome) and nitromersol (Metaphen). Thimerosal disinfects by the action of the mercury in the molecule, which precipitates the protein of a microorganism and disrupts its metabolism. Thimerosal occurs as a light-coloured crystalline powder, soluble in water and in alcohol. It is used as a 0.1 percent alcoholic tincture or aqueous solution
