Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Density at 20°C = 0.96 kg/m3 [Safepharm, 2007; Read-across data from C8 isomer]
Further information:
1) Relative density at 15.6 °C = 0.96 [Adams, 2012]
2) Relative density = 1.03 (at 20 °C) [Safepharm, 2007; Read-across data from C4 isomer]

Key value for chemical safety assessment

Relative density at 20C:

Additional information

Key value:

Density of the target UVCB substance at 20°C is expected to be close to that of "C8" substance (CAS 144429 -84 -5).

Density of the target UVCB substance at 15.6°C is determined to be 0.96 kg/m³ (relative density 0.96).
