Parathion Chemical Properties,Uses,Production


Parathion is an organophosphate insecticide used on cotton, rice and fruit trees.


Insecticide; acaricide.

General Description

Light-yellow liquid, Parathion turn solid at 6° C, a deadly poison by all routes. Organic phosphate insecticide, acts as an inhibitor of cholinesterase.

Air & Water Reactions

Parathion is slightly soluble in water.

Reactivity Profile

Violent reaction when PARATHION is used as solvent to dissolve endrin. When heated to decomposition Parathion emits very toxic fumes of oxides of sulfur, phosphorus and nitrogen [Lewis, 3rd ed., 1993, p. 984].

Health Hazard

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
