Paraquat (trivial name; /ˈpærəkwɒt/) or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name) is an organic compound with the chemical formula [(C₆H₇N)₂]Cl₂. It is classified as a viologen, a family of redox-active heterocycles of similar structure. Paraquat was manufactured by Chevron. This salt is one of the most widely used herbicides. It is quick-acting and non-selective, killing green plant tissue on contact. It is also toxic to human beings and animals due to its redox activity, which produces superoxide anions. It has been linked to the development of Parkinson's disease and is banned in several countries.
