Additional information

Exploring QSAR , Hydrophobic, Electric, and Steric Constants by Hansch et al. (1995) is a peer reviewed handbook and is considered reliable and suitable for use as the key study for this endpoint.

The supporting study (CRC, 2008) is also a peer reviewed handbook and supports the value reported in the key study, giving a partition coefficient of 2.73.
