CAS 298-00-0: Parathion-methyl

Description: Parathion-methyl, with the CAS number 298-00-0, is an organophosphate compound primarily used as an insecticide. It is characterized by its high toxicity to a wide range of pests, making it effective in agricultural applications. The chemical structure of parathion-methyl includes a phosphate group, which is responsible for its mode of action as an acetylcholinesterase inhibitor, leading to the accumulation of acetylcholine in the nervous system of insects. This results in paralysis and death of the target organisms. Parathion-methyl is a colorless to pale yellow liquid with a faint odor, and it is relatively insoluble in water but soluble in organic solvents. Due to its high toxicity, it poses significant risks to human health and the environment, leading to strict regulations regarding its use and handling. Safety measures are essential when working with this substance, as exposure can result in severe health effects, including respiratory distress and neurological symptoms. Consequently, its use has been restricted or banned in many countries.
