CAS 2921-88-2: Chlorpyrifos

Description: Chlorpyrifos is an organophosphate insecticide widely used in agriculture for pest control. It is characterized by its ability to inhibit the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system of insects, which ultimately results in their death. Chlorpyrifos is a colorless to yellowish liquid with a faint, sulfurous odor, and it is relatively stable under normal conditions. Its chemical formula is C9H11Cl3NO4PS, indicating the presence of chlorine, phosphorus, and sulfur in its structure. The substance is moderately soluble in water but more soluble in organic solvents, which affects its application and environmental behavior. Chlorpyrifos has raised environmental and health concerns, leading to regulatory scrutiny and restrictions in several countries due to its potential neurotoxic effects on humans and wildlife. Its persistence in the environment can lead to contamination of soil and water, prompting ongoing research into safer alternatives for pest management.
