Molecular Structure
Physical Properties
Molecular weight:409.8; Physical form:Tech. is a viscous amber liquid. Density:1.59-1.63 (25 °C, tech.); Composition:Chlordane contains 60-75% of chlordane isomers, the major components being two stereoisomers whose nomenclature at C(1) and C(2) has been confused in the literature: the alpha or cis- isomer (1a,2a,3aa,4bcis- isomer 106-107 °C; trans- isomer 104-105 °C; Vapour pressure:1.3 mPa (25 °C) (pure); Henry constant:5.33 Pa m3 mol-1 (calc.); Solubility:In water 0.1 mg/l (25 °C). Miscible with most aliphatic and aromatic organic solvents, including acetone, cyclohexanone, ethanol, deodorised kerosene, isopropanol, trichloroethylene.; Stability:Decomposed by alkalis, with the loss of chlorine. Under u.v. irradiation, a change in the skeletal structure and of the chlorine content occurs.
Toxicology
Oral:Acute oral LD50 for rats 133-649 mg/kg, mice 430 mg/kg, rabbits 300 mg/kg. Percutaneous:Acute percutaneous LD50 for rabbits 200-2000 mg/kg, rats 217 mg/kg. Extremely irritating and corrosive to eyes; not a skin irritant (rabbits). Non-sensitising to skin (guinea pigs). Inhalation:LC50(4 h) for rats 0.56 mg200 mg/l (nominal). Phytotoxicity:Non-phytotoxic when used as directed. High concentrations may cause injury to some vegetables. Soil residues may depress
Environmental Profile
Ecotoxicology: Bees:Toxic to bees.Birds:Acute oral LD50 for bobwhite quail 83 mg/kg. Dietary LC50 (8 d) for bobwhite quail 421, mallard ducks 795 mg/kg diet.Daphnia:LC50 (48 h) 0.59 mg/l.Fish:LC50 (96 h) for rainbow trout 0.09, bluegill sunfish 0.07 mg/l.Bee: Toxic. Environmental fate: Animals:In rats, following oral administration, chlordane is metabolised via 1,2-dichlorochlordene and oxychlordane to 1-exo-hydroxy-2-chlorochlordene and 1-exo-hydroxy-2-endo-chloro-2,3-exo-epoxychlordene, and to various otherSoil:DT50 in soil c. 1 y.
