81532-47-0 Usage
General Description
2-Chloro-4-methoxy-5H,6H,7H-cyclopenta[d]pyrimidine, also known as Clorpyrifos, is a chemical compound that is commonly used as a pesticide. It belongs to the class of organophosphate insecticides and is widely used to control a variety of pests in agricultural and residential settings. Clorpyrifos works by disrupting the nervous system of insects, ultimately leading to their death. However, it is also toxic to humans and animals, and its use has raised concerns about its potential health effects. In 2021, the United States Environmental Protection Agency (EPA) revoked all food tolerances for Clorpyrifos due to its potential risks to human health, particularly for children and agricultural workers. Despite this, Clorpyrifos is still used in other countries and continues to be the subject of regulatory and public health debates.
