C10H18Cl3N

C10H18Cl3N is a chemical compound belonging to the class of organochlorine compounds, characterized by its molecular formula consisting of ten carbon atoms, eighteen hydrogen atoms, three chlorine atoms, and one nitrogen atom. This compound is commonly known as **chlorpyrifos-methyl**, a widely used organophosphate insecticide. It was developed in the mid-20th century and has been utilized extensively in agriculture to control a variety of pests, including insects that affect crops such as cotton, corn, and fruits.

Chlorpyrifos-methyl functions primarily by inhibiting acetylcholinesterase, an enzyme critical for nerve signal transmission in insects and mammals. By disrupting this enzyme, it leads to overstimulation of the nervous system, ultimately causing paralysis and death in target pests. Due to its broad-spectrum efficacy, it has been employed not only in farming but also in non-agricultural settings, such as household pest control.

Regulatory scrutiny of chlorpyrifos-methyl has increased over time due to concerns regarding its environmental and health impacts. Studies have linked exposure to developmental and neurological effects in humans, particularly in children, prompting restrictions in several countries. In 2021, the U.S. Environmental Protection Agency (EPA) issued a ban on most agricultural uses of chlorpyrifos, citing risks to public health. However, some uses, particularly in non-agricultural settings, remain permitted under specific regulations.

The compound is typically applied as an emulsifiable concentrate or ultra-low-volume formulation, ensuring effective distribution and absorption by target organisms. Its chemical structure contributes to its persistence in the environment, raising concerns about long-term ecological effects. Due to its regulated status, research and development efforts have shifted toward alternative, less hazardous insecticides to mitigate risks associated with chlorpyrifos-methyl.
