Description of key information

The adsorption coefficient Koc of the test substance was analyzed according to OECD 121 and EU Method C 19. An HPLC method consisting of Hypersil BDS-CN column as the stationary phase and 55:45 MeOH:water as the mobile phase was used. Both UV and MS detection system were utilized to estimate the concentration of the main components in the substance. Only one of the components could be detected that corresponded to a Koc of 1.0 x 105 or logKoc of 5.01. The other components were deemed to have even higher Koc values. As a result, the logKoc of the test substance is estimated at >5.01

Key value for chemical safety assessment

Koc at 20 °C:
