Parathion, an organophosphate pesticide, known for its effectiveness against various agricultural pests, is characterized by its strong insecticidal activity. Despite its efficacy, parathion's significant toxicity to humans and environmental hazards have led to its prohibition as a pesticide under various regulations.
Previously used across various crops for pest control, parathion's use has been curtailed due to its high toxicity levels. It was effective against pests such as psyllids and water bugs but is now largely restricted to specific non-agricultural applications and as a reference substance in pesticide residue analysis.

With low water solubility and high solubility in various organic solvents, parathion poses a flammability risk at elevated temperatures, releasing toxic gases when decomposed.
Parathion's extensive classification under the GHS system underscores its severe toxicity to both human health and the environment, necessitating stringent handling and protective measures to mitigate exposure risks.
Given its classification as a specific poisonous substance, handling parathion requires comprehensive safety precautions, including personal protective equipment and proper ventilation, to protect against its acute toxicity and potential health impacts.
The environmentally hazardous nature of parathion demands that disposal is managed by professional waste disposal services, adhering to regulations to prevent environmental contamination.
Known also by names such as ethyl parathion and O,O-diethyl-O-(4-nitrophenyl)phosphorothioate, parathion's regulated status is reflected across safety data sheets and regulatory documents, emphasizing the need for careful compliance with health and safety standards.
