Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

log Octanol-water partition coefficient [furan]: 1.34

Key value for chemical safety assessment

Log Kow (Log Pow):

Additional information

A log Kow of 1.34 (Hansch 1995) was reported for the substance in a collection of data which has been subject to peer review and in which the original sources are traceable. The result is considered reliable and selected as key study. This is supported by a predicted log Kow value of 1.36 (PFA 2012) which was determined for the substance using a validated QSAR estimation method. In other secondary sources to which reliability could not be assigned, log Kow values of 1.33 - 1.34 (Hulzebos 1993) and 1.34 - 1.35 (Pennakem 2011) were reported for the substance.
