CAS 21609-90-5: Leptophos

Description: Leptophos, with the CAS number 21609-90-5, 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 crucial for the proper functioning of the nervous system in insects, leading to paralysis and death. Leptophos is typically a colorless to pale yellow liquid with a distinctive odor, and it is soluble in organic solvents but has limited solubility in water. Its chemical structure includes a phosphorus atom bonded to various organic groups, contributing to its biological activity. Due to its mode of action, Leptophos is effective against a wide range of pests, but it also poses potential risks to non-target organisms, including humans and wildlife, necessitating careful handling and application. Regulatory agencies often monitor its use to mitigate environmental impact and ensure safety. As with many pesticides, proper safety measures and adherence to guidelines are essential when using Leptophos in agricultural practices.
