CAS 55-38-9: Fenthion

Description: Fenthion is an organophosphate compound primarily used as an insecticide and acaricide in agricultural practices. It is characterized by its ability to inhibit acetylcholinesterase, an enzyme crucial for the proper functioning of the nervous system in insects, leading to paralysis and death. Fenthion is typically a colorless to pale yellow liquid with a faint odor, and it is soluble in organic solvents but has limited solubility in water. Its chemical structure includes a thiophosphate group, which contributes to its biological activity. Fenthion is known for its effectiveness against a wide range of pests, including aphids, mites, and various agricultural insects. However, it poses potential risks to non-target organisms, including humans and wildlife, due to its toxicity. As a result, its use is regulated in many countries, and safety precautions are essential when handling this substance. Environmental persistence and potential for bioaccumulation are also considerations in its application and management in agricultural settings.
