Methyl Parathion

Methyl parathion is an organophosphate insecticide. Methyl parathion is lethal to lab strains and field isolates of tobacco budworm larvae (LD50s = 7 and 81.8-128.3 µg/g, respectively). It reduces the number of stink bugs (C. sayi) caught per 100 net sweeps when applied to alfalfa fields at a concentration of 0.4 pounds per acre. Methyl parathion increases sister chromatid exchange (SCE) in a concentration-dependent manner and induces cell cycle arrest at the M1 phase in V79 cells at a concentration of 40 µg/ml. It is toxic to rats (LD50 = 14 mg/kg).Formal Name: phosphorothioic acid, O,O-dimethyl O-(4-nitrophenyl) ester. CAS Number: 298-00-0. Synonyms: BAY 11405. Molecular Formula: C8H10NO5PS.
