The study was conducted following OECD guideline 107 and EEC method A8.
Measured volumes of the test substance in n-octanol (saturated with water) were shaken with measured volumes of purified water (saturated with n-octanol) for 5 minutes. The mixtures were transferred to centrifuge tubes and equilibrated at 20°C for 18 hours prior to centrifugation at 2500 rpm for 10 minutes at 20°C. Following separation, the aqueous phases were filtered and an aliquot (10 mL) of each extracted with two portions (25 mL) of dichloromethane. The combined extracts were evaporated to dryness under nitrogen at 40°C and re-dissolved in diluent solution (0.5 mL) containing octanophenone (internal standard) for analysis by HPLC. Recoveries were determined by extracting purified water (20 ml) fortified with test substance at the anticipated solubility level (5 mg/L), then extracting and preparing the samples for analysis as above.
Samples (1 mL) of the n-octanol phases were added to internal standard solution (1 mL) and diluted to volume (25 mL) with diluent solution for analysis by HPLC.
Partition coefficient: log Kow = 4.00; Equivalent Kow = 9890.
