Mesulfenfos

Description:
Mesulfenfos, with the CAS number 3761-41-9, 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. Mesulfenfos is typically a colorless to pale yellow liquid with a distinctive odor. Its chemical structure includes a phosphorus atom bonded to sulfur and various organic groups, which contribute to its biological activity. The compound is moderately soluble in organic solvents but has limited solubility in water, affecting its application and environmental behavior. Safety precautions are necessary when handling mesulfenfos, as it can be toxic to non-target organisms, including humans and wildlife, if not used according to guidelines. Its use is regulated in many countries to mitigate potential environmental and health risks associated with pesticide exposure.
