Organophosphorus compound

Organophosphorus compounds are a group of organic compounds containing phosphorus. They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment. Some organophosphorus compounds are highly effective insecticides, although some are extremely toxic to humans, including sarin and VX nerve gases.

Organophosphorus chemistry is the science of the properties and reactivity of organophosphorus compounds. It is the basis for many important biochemicals, including DNA and RNA.

History

Organophosphorus compounds have been known since the 19th century. There are few examples of naturally occurring organophosphorus compounds. The majority of these compounds are synthesized for their effective insecticidal properties.

Structure and classification

Organophosphorus compounds can be classified in several ways, including the presence of substituents on the phosphorus or the nature of the phosphorus-carbon bond.

Uses

Organophosphorus compounds have many uses, including in warfare, pest control, and neuroscience.

Health effects

Exposure to organophosphorus compounds can be harmful to human health. Some of these compounds are extremely toxic and have been used as nerve gases.
