Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Executive summary:
Method
Relative density was determined by means of a pycnometer as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.
Result
Relative density: 1.248 at 20 °C.
Reference
Absolute density of a substance (δ) is calculated as:
δ subs = WS / V subs = WS / (V pyc – V hex ) = WS / (V pyc – WH2 / δ hex ) = WS / (V pyc – WH 2 × V pyc / WH1 ) Relative density (D204) is calculated as: δ subs / 0.999973

Description of key information
Key value for chemical safety assessment
- Relative density at 20C:
- 1.248
Additional information
Relative density was determined by means of a pycnometer as per recommendations of OECD 109. Relative density was calculated from the difference in weight between the full and empty pycnometer and its volume and resulted 1.248.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
