Chlorpyrifos

Fabricate a 3D molecular structure model of Chlorpyrifos out of Authentic Molymod Components by Indigo Instruments

Chlorpyrifos is an insecticide, acaricide, & miticide. It is an acetylcholinesterase inhibitor used to control soil borne pests. It is an organic thiophosphate based whose structure is classed as a chloropyridine.

Among the most common acetylcholinesterase inhibitors are phosphorus-based compounds, which are designed to bind to the active site of the enzyme. The structural requirements are a phosphorus atom bearing two lipophilic groups, a leaving group (such as a halide or thiocyanate), and a terminal oxygen.

For the past 20 years it was topic of debate and untlimately banned in 2021 in the US for use on food crops. Since then, ongoing litigation sees this ban still not in full force.
