Description of key information

The organic carbon water partition coefficient (Koc) of 1,2 -dichloro-1 -[difluoro(trifluoromethoxy)methoxy]-1,2,2-trifluoroethane is calculated to be 2030 by QSAR (Ref: EUSES 2.1.2.), corresponding to Log Koc = 3.30.

The value indicates that the substance has a certain affinity for Organic Carbon.

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

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

EUSES estimation provides a value of Koc = 2030 for 1,2 -dichloro-1 -[difluoro(trifluoromethoxy)methoxy]-1,2,2-trifluoroethane, corresponding to Log Koc = 3.30 indicating that substance has a certain affinity for Organic Carbon.
