Usage

Description

O,O-dipropyl chlorothiophosphate, commonly known as chlorpyrifos, is a highly toxic organophosphate pesticide that is utilized for controlling pests on a wide range of crops. It functions as a cholinesterase inhibitor, which means it interferes with the nervous system's operation by hindering the breakdown of the neurotransmitter acetylcholine. This pesticide is characterized by its significant potential to cause harm to both human health and the environment.

Uses

Used in Agricultural Industry:
O,O-dipropyl chlorothiophosphate is used as a pesticide for controlling a broad spectrum of pests in various agricultural settings. It is applied to protect crops from damage caused by insects, which can lead to increased yields and improved crop quality.
However, due to the associated health risks and environmental concerns, the use of O,O-dipropyl chlorothiophosphate has faced increasing restrictions in many countries. This has led to a push for the development of alternative, safer pest control methods that minimize the impact on human health and the environment.

Reaction of Thiolo and Selenolo Esters of Phosphorus Acids with Halogens. Part 3. Interaction of O,O,S-Trialkyl Phosphorothioates and O,S-Dialkyl t-Butylphosphonothioates with Sulphuryl Chloride and Halogens

The reaction of the title phosphono- and phosphoro-thiolates with sulphuryl chloride and halogens involves in every case the formation of intermediates containing two phosphorus atoms >P+(SR)OP(O)- (X = SO2Cl or halogen).The formation of the latter in the course of chlorinolysis of phosphorus thiolesters is suggested to be responsible for the occurrence of a mechanism involving retention of configuration.The effect of the structure of the reactants and the nature of solvent on the reaction stereochemistry is discussed.
