Methyl dichlorothiophosphate

Description:

Methyl dichlorothiophosphate, with the CAS number 2523-94-6, is an organophosphorus compound primarily used as an insecticide and acaricide in agricultural applications. It is characterized by its chemical structure, which includes a phosphorus atom bonded to two chlorine atoms and a methyl group, along with a thiophosphate moiety. This compound is typically a colorless to pale yellow liquid with a pungent odor. It is soluble in organic solvents but has limited solubility in water. Methyl dichlorothiophosphate acts by inhibiting acetylcholinesterase, an enzyme crucial for the proper functioning of the nervous system in insects, leading to paralysis and death. Due to its potential toxicity to non-target organisms, including humans, it is subject to strict regulatory controls. Proper handling and safety measures are essential when working with this substance, as it can pose health risks through inhalation, skin contact, or ingestion. Environmental persistence and potential bioaccumulation are also important considerations in its use and management.
