CAS 563-12-2: Ethion

Description: Ethion, with the CAS number 563-12-2, 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. Ethion is typically a colorless to pale yellow liquid with a faint odor and is soluble in organic solvents but has limited solubility in water. Its chemical structure includes a thiophosphate group, which contributes to its biological activity. Ethion is known for its effectiveness against a variety of pests, including aphids, mites, and certain beetles, making it valuable in crop protection. However, it is also associated with potential environmental and health risks, necessitating careful handling and application practices. Regulatory agencies often monitor its use to mitigate risks to non-target organisms and human health. As with many pesticides, the development of resistance in target pest populations is a concern, prompting ongoing research into alternative pest management strategies.
