This chemical is primarily used as an antidote for poisoning by organophosphate compounds, which are found in certain pesticides and nerve agents. It works by reactivating the enzyme acetylcholinesterase, which is inhibited by organophosphates, thereby restoring normal nerve function. Additionally, it is employed in research settings to study the mechanisms of nerve agents and to develop more effective treatments for poisoning. Its application is critical in medical and military contexts where exposure to these toxic substances is a risk.
