Methylmercury is an organometallic cation with the formula . It is the simplest organomercury compound. Methylmercury is extremely toxic, and its derivatives are the major source of organic mercury for humans. It is a bioaccumulative environmental toxicant with a 50-day elimination half-life in human blood. Methylmercury salts along with dimethylmercury are the causative agents of the infamous Minamata disease.
