ABSTRACT
CASRN: 636-28-2; molecular formula: C6H2Br4; FW: 393.70 Physical state: Solid Melting point (°C): 180-182 (Acros Organics, 2002) 189 (Weast, 1986) Boiling point (°C): 329 (Weast, 1986) Diffusivity in water (x 10-5 cm2/sec): 0.61 at 20 °C using method of Hayduk and Laudie (1974) Bioconcentration factor, log BCF: 3.57-3.81 (rainbow trout, Oliver and Niimi, 1985) 3.45 (wet weight based), 0.92 (lipid based) (Gambusia affinis, Chaisuksant et al., 1997) Ionization potential (eV): 8.65, 8.89 (Mallard and Linstrom, 1998) Soil organic carbon/water partition coefficient, log Koc: 4.82 using method of Chiou et al. (1979) Octanol/water partition coefficient, log Kow: 5.13 at 25 °C (shake flask-GC, Watarai et al., 1982) 5.25 (generator column-HPLC, Garst, 1984) Solubility in organics: Soluble in alcohol, benzene, and ether (Weast, 1986) Solubility in water: 40 µg/L at 20-25 °C (Kim and Saleh, 1990) 104.7 nmol/L at 25 °C (shake flask-UV spectrophotometry, Yalkowsky et al., 1979) Environmental fate: Chemical/Physical. 1,2,4,5-Tetrabromobenzene (150 mg in 250-mL distilled water) was stirred in the dark for 1 day. GC analysis of the solution showed 1,2,4-tribromobenzene as a major transformation product (Kim and Saleh, 1990). Uses: Organic synthesis.
