Description of key information

The organic carbon - water partition coefficient (Koc) of 1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane is calculated to be 119 by QSAR (Ref: EUSES 2.1.2.), corresponding to Log Koc = 2.08.

The value indicates that the substance has a limited affinity for Organic Carbon ant it would be mobile in soil.

Key value for chemical safety assessment

Koc at 20 °C:
119

Additional information

The organic carbon water partition coefficient (Koc) of 1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane is calculated by QSAR (Ref: EUSES 2.1.2.) basing on the Partition coefficient Octanol - water (Kow) and considering that 1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane owns to the class of non-hydrophobic substances.

EUSES estimation provides a value of Koc = 119 for 1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane, corresponding to Log Koc = 2.08 indicating that substance has a limited affinity for Organic Carbon ant it would be mobile in soil.
