Useful:

Chemical Classes:Pesticides -> Organophosphate Insecticides
Canonical SMILES:CCOP(=S)(OCC)OC1=CC=C(C=C1)[N+](=O)[O-]
Inhalation Risk:Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.
Effects of Short Term Exposure:The substance may cause effects on the nervous system. This may result in convulsions, respiratory failure and muscle weakness. Cholinesterase inhibition. Exposure could cause death. The effects may be delayed. Medical observation is indicated.
Effects of Long Term Exposure:Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.
Description After exposure to parathion ethyl, one case of a bullous contact dermatitis was reported.
Physical properties Pale yellow to dark brown liquid with a garlic-like odor. Robeck et al. (1965) reported odor threshold concentrations of 3 and 36 ppm for technical and pure grades, respectively.
Uses Parathion is used to control sucking and chewing insects, mites and soil insects in a very wide range of crops. Parathion is an organophosphate insecticide used on cotton, rice and fruit trees. Insecticide; acaricide.
