Ethylmercury (sometimes ethyl mercury) is a cation composed of an ethyl group and a mercury atom; its chemical formula is C₂H₅Hg⁺. The term 'ethylmercury' is sometimes used as a generic term to describe organomercury compounds which include ethylmercury such as ethylmercury chloride and ethylmercury urea. The CAS registry number for ethylmercury chloride is [107-27-7] [1]. IUPAC nomenclature is a system of naming chemical compounds and of describing the science of chemistry in general. ... A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. ... The molecular mass (abbreviated MM) of a substance, called molecular weight and abbreviated as MW, is the mass of one molecule of that substance, relative to the unified atomic mass unit u (equal to 1/12 the mass of one atom of carbon-12). ... Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. ... The melting point of a solid is the temperature at which it changes state from solid to liquid. ... The boiling point of a substance is the temperature at which it can change its state from a liquid to a gas throughout the bulk of the liquid at a given pressure. ...

Ethylmercury is one of the metabolites of thiomersal, which is used as a preservative in some vaccines. For this application, the ethylmercury salt sodium ethylmercuric thiosalicylate is used. Thimerosal (C₉H₉HgNaO₂S) is made from the combination of ethyl mercuric chloride, thiosalicylic acid, sodium hydroxide and ethanol. Metabolites are the intermediates and products of metabolism. ... The structure of Thimerosal Thimerosal (sometimes spelled as thimerosol and thiomersal[1]) (trade name: Merthiolate) is an organometallic compound used commonly since the 1930s as a preservative in some vaccines. ... A magnified crystal of a salt (halite/sodium chloride) In chemistry, a salt is any ionic compound composed of positively charged cations and negatively charged anions so that the product is neutral and without a net charge. ... Mercury(II) chloride (also called mercuric chloride and corrosive sublimate) is a poisonous white soluble crystalline sublimate of mercury. ... Sodium hydroxide (NaOH), also known as lye or caustic soda, is a caustic metallic base. ... This article is about the chemical compound. ...

Unlike methylmercury, ethylmercury has not been found to bioaccumulate^[1]. The toxicity of ethylmercury is not well studied, however exposure standards based on methylmercury (such as those currently recommended by the EPA) are not demonstrated to be equivalent for ethylmercury^[2]. Methylmercury (sometimes methyl mercury), an organometallic positive ion (cation), is a widespread bioaccumulative environmental toxin. ... To bioaccumulate literally means to accumulate in a biological system. ... EPA redirects here. ...
