Description of key information

The HPLC method (in accordance with EC C.19 and OECD 121 and in compliance with GLP) was performed to determine the adsorption coefficient (soil) of the test substance. The HPLC chromatogram of the test solution showed four major peaks (with peak areas of 52%, 38%, 4.9% and 2.4%). The log Koc for the major peaks were 2.22, 2.44, 2.51 and 2.67, respectively.

The weight-averaged logKoc value considering the four main components has been derived to be 2.33 (= log 214). HPLC column temperature: 35°C ± 1°C, while it is considered that the Koc values of the reference substances, as reported in the OECD 121, have been determined at 20 °C.
