CAS 5871-17-0: Potassium O,O-diethylthiophosphate
Description:Potassium O,O-diethylthiophosphate, with the CAS number 5871-17-0, is an organophosphate compound characterized by its role as a pesticide and insecticide. It is a salt formed from the reaction of diethylthiophosphate with potassium. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its formulation. It is soluble in water and organic solvents, which enhances its utility in agricultural applications. The chemical structure features a phosphorus atom bonded to two ethyl groups and a thiophosphate moiety, contributing to its biological activity. Potassium O,O-diethylthiophosphate acts by inhibiting acetylcholinesterase, an enzyme critical for nerve function, leading to the disruption of neurotransmission in pests. While effective in pest control, it is important to handle this substance with care due to its potential toxicity to non-target organisms, including humans and wildlife. Proper safety measures and regulations are essential when using this compound in agricultural practices.
