Parathion, also called parathion-ethyl or diethyl parathion, is an organophosphate compound. It is a potent insecticide and agaricide. It was originally developed by IG Farben in the 1940s. It is highly toxic to non-target organisms, including humans. Its use is banned or restricted in many countries, and there are proposals to ban it from all use. However, it is very toxic in nature and thus its analysis is of tremendous importance. The goal of the present investigation is basic cum applied in nature and it aims at the development of chemically modified electrode for ethyl parathion.
