Mol. wt.: 331.4; M.f.: C19H25NO4; Form: Colourless crystals, with slight pyrethrum-like odour; (tech. is a colourless to light yellow-brown solid). M.p.: 68-70 °C; (tech., 60-80 ºC). V.p.: 2.1 mPa (25 °C). KOW: logP = 4.6 (25 ºC). S.g./density: 1.1 (20 ºC). Solubility: In water 1.83 mg/l (25 ºC). In acetone, ethanol, methanol, hexane, n-octanol all >2 g/100 ml. Stability: Sensitive to alkalis and strong acids; DT50 16-20 d (pH 5), 1 d (pH 7), 5000 mg/kg. Skin and eye: Acute percutaneous LD50 for rabbits >2000 mg/kg. Non-irritant to skin. Inhalation: LC50 (4 h) for rats >2.73 mg/l air. NOEL: In 13 w feeding trials, dogs receiving 5000 mg/kg diet showed no ill-effects. In 6 mo feeding trials, no-effect level for rats was 1500 mg/kg diet. Other: No evidence of oncogenicity. Toxicity class: WHO (a.i.) III (Table 5); EPA (formulation) IV ECOTOXICOLOGY Birds: Acute oral LD50 for bobwhite quail >2250 mg/kg. Dietary LC50 for bobwhite quail and mallard ducks >5620 ppm. Fish: LC50 (96 h) for rainbow trout 3.7, bluegill sunfish 16 ug/l. Daphnia: EC50 (48 h) 0.11 mg/l. Bees Toxic to bees. ENVIRONMENTAL FATE Animals: In rats, following oral administration, around 95% of tetramethrin (metabolised) is eliminated in the urine and faeces within 5 days. The principal metabolite is 3-hydroxycyclohexan-1,2-dicarboximide. Soil/Environment: Degradation involves cleavage of the ester bond, leading to chrysanthemic acid derivatives and phenoxybenzoic acid. These are further metabolised by hydroxylation and conjugation.
