Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Vapour pressure = 2.0 x 10E-5 Pa (at 25 °C) [Safepharm, 2007; Read-across data from C8 isomer]
Further information:
1) Vapour pressure = 1.2 x 10-4 Pa (at 25 °C) [Safepharm, 2007; Read-across data from C4 isomer];
2) Vapour pressure = 1.51E-7 (at 25°C) [calculated for C9 constituent of isomeric mixture, EIWIN, Chemservice S.A., 2011]

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

Vapour pressure of the target UVCB substance is expected to be close to that of "C8" substance (CAS 144429 -84 -5).
