Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Density: 1.020 ± 0.001 g/cm3 at 20.6 °C
Key value for chemical safety assessment
Additional information
A relative density of 1.02 at 20.6 °C was determined by an appropiate guideline method. The result is considered to be reliable and is assigned as the key study.
A predicted density of 0.95 g/cm3 at 20 °C was determined for the substance as a supporting study using a validated QSAR estimation method. The result is considered to be reliable.
In a secondary source to which reliability could not be assigned, density value of 1.02 g/mL at 25 °C was reported for the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
