Mol. wt.: 324.7; M.f.: C9H10ClN2O5PS; Form: Colourless crystals; (tech. is a beige to grey powder). M.p.: 89 ºC. V.p.: 0.0049 mPa (20 ºC). KOW: logP = 1.05; Henry: 1.45x10-6 Pa m3 mol-1 (calc.) S.g./density: 1.60 (20 ºC). Solubility: In water 1.1 g/l (pH 7, 20 ºC). In dichloromethane 610, benzene 130, methanol 100, n-octanol 5.8 (all in g/kg, 20 ºC). Stability: Unstable in acids and alkalis; DT50 (20 ºC) (calc.): 800 h (pH 5), 260 h (pH 7), 4.3 h (pH 9). F.p.: >150 °C (Marcusson, without stirring). APPLICATIONS Biochemistry: Cholinesterase inhibitor. Mode of action: Insecticide with contact and stomach action. Gives rapid knockdown, and has good residual activity. Uses: Control of flies and other insect pests in animal houses. Control of mosquitoes, tsetse flies, cockroaches, and other public hygiene pests. Formulation types: AE; WP. MAMMALIAN TOXICOLOGY Oral: Acute oral LD50 for rats 1180 mg/kg. Skin and eye: Acute percutaneous LD50 for rats >2150 mg/kg. Mild eye irritant; non-irritating to skin (rabbits). Inhalation: LC50 (4 h) for rats >560 mg/m3 air. NOEL: (90 d) for rats 20 mg/kg diet (2 mg/kg daily), for dogs 10 mg/kg diet (0.3 mg/kg daily). ADI: 0.025 mg/kg. Toxicity class: WHO (a.i.) III; EPA (formulation) III ECOTOXICOLOGY Birds: Acute oral LD50 for bobwhite quail 30.2, mallard ducks 48.4 mg/kg. Dietary LC50 (8 d) for bobwhite quail 860, Japanese quail >1000, mallard ducks 700 ppm. Based on the results of acute laboratory trials, azamethiphos is classified as highly toxic to birds. However, sublethal doses have a repellent effect on birds, so the risk for birds is significantly reduced. Fish: LC50 (96 h) for channel catfish 3, crucian carp 6, guppy 8, rainbow trout 0.115-0.2, sheepshead minnow 2.22 mg/l. Based on the test with the most sensitive species, rainbow trout, azamethiphos is classified as highly toxic to fish. All other test species were less sensitive to this compound. Daphnia: LC50 (48 h) 0.67 ug/l. Bees: Toxic to bees; LD50 (24 h) (oral)
