Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key information:
Log Pow at 30 °C = 7.18 (HPLC) [Safepharm, 2007; Read-across data from C8 isomer]
Further information:
1) Log Pow at 19.5 °C > 4.06 (shake-flask) [Safepharm, 2007; Read-across data from C4 isomer]
2) LogPow = 8.99 (calculated for C9 constituent of isomeric mixture, EPIWIN, Chemservice S.A., 2011]

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
30 °C

Additional information

Key value: Partition coefficient of the target UVCB substance is expected to be close to that of "C8" substance (CAS 144429 -84 -5).
