Description

Diazinon is an organophosphate insecticide widely used in agriculture to control a variety of pests. It acts by inhibiting the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system of insects, ultimately resulting in their paralysis and death.

Diazinon Use and Manufacturing

Methods of Manufacturing

Methanol, hydrogen chloride and isobutyronitrile are reacted to form the corresponding imidate hydrochloride; treated with ammonia and converted into the corresponding amidine. Then, under basic conditions, amidine is condensed with ethyl acetoacetate to obtain pyrimidinol (4-hydroxy-2-isopropyl-6-methylpyrimidine). Pyrimidinol is heated to reflux in the presence of sodium carbonate in benzene or toluene, diethylthiophosphoryl chloride and copper nitrate are added, and condensation is obtained to obtain diazinon.

Uses

Diazinon is primarily used for controlling pests in crops such as fruits, vegetables, and ornamentals. It is also used in residential pest control, particularly for ants, cockroaches, and other household insects. However, due to environmental and health concerns, its usage has been restricted in many countries.
