Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 pycnometer method 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: 1.732 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
