Pyridaphenthion

Description:
Pyridaphenthion, with the CAS number 119-12-0, is an organophosphorus compound primarily used as an insecticide and acaricide in agricultural applications. It is characterized by its ability to inhibit acetylcholinesterase, an enzyme critical for the proper functioning of the nervous system in insects, leading to paralysis and death. The compound typically appears as a pale yellow to brown solid and is known for its moderate to high toxicity to various non-target organisms, including aquatic life. Pyridaphenthion is soluble in organic solvents but has limited solubility in water, which influences its environmental behavior and persistence. Its use is regulated in many countries due to potential health risks to humans and wildlife, necessitating careful handling and application practices. Additionally, it is important to consider its degradation products and the potential for bioaccumulation in the ecosystem. Overall, while effective as a pesticide, the environmental and health implications of Pyridaphenthion require thorough assessment and management.
