Description of key information

TFE does not contain any hydrogen or hydroxyl groups and will not dissociate into a conjugate base and proton or conjugate acid and hydroxyl ion. Therefore it is not possible to measure a dissociation constant.

Key value for chemical safety assessment

Additional information

According to REACH Annex IX, 7.16, Column 2, the study does not need to be done if scientifically not possible. TFE does not contain any hydrogen or hydroxyl groups and will not dissociate into a conjugate base and proton or conjugate acid and hydroxyl ion. Therefore it is not possible to measure a dissociation constant.
