Useful:

• Chemical Classes: Pesticides -> Organophosphate Insecticides
• Canonical SMILES: CC(=CC(=O)N(C)C)OP(=O)(OC)OC
• Isomeric SMILES: C/C(=C\C(=O)N(C)C)/OP(=O)(OC)OC
• 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 and respiratory failure. Cholinesterase inhibition. Exposure far above the OEL 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: It is a yellowish liquid, bp 130 ?C/0.1 mmHg, vp 9.3 mPa (20 ?C). It ismiscible with water and most organic solvents except kerosene. Log Kow = ?0.5. Dicrotophos is rather stable to heat and slowly hydrolyzed in acidic media and more rapidly in alkaline media; DT50 (20 ?C) at pH 5, 7, and 9 are 88, 72, and 28 d, respectively.
• Uses: Contact and systemic insecticide and acaricide used to control pests on rice, cotton, maize, soybeans, coffee, citrus and potatoes. Dicrotophos is used to control sucking, chewing and boring insects and mites in a wide range of crops. It is also used as an animal ectoparasiticide.
