Description of key information

This information requirement is waived, on the basis that such mesurement for a substance which does not possess ionizable functional groups is scientifically unjustified.

Key value for chemical safety assessment

Additional information

Since biphenyl will not dissociate in water (due to a lack of ionoizable functional groups) it will technically not be possible to determine the pKa of this substance.
