In the key study the partition coefficient of the test material was
investigated using the HPLC method in accordance with standardised
guidelines. The retention time of the test material on the column was
compared to that of the reference material 4,4’-DDT using 75 % methanol
as the mobile phase at neutral pH. Under these analytical conditions,
the test material could not be eluted form the column, whereas 4,4’-DDT
(log Pow = 6.5) had a retention time of 18.4 minutes. It was therefore
concluded that the test material had a higher log Pow than the reference
material. Under the conditions of this study, the partition coefficient
of the test material is log Pow >6.5 (Pow >3.2 x 10⁶).
