Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The relative density was determined by means of a pycnometer as per recommendations of OECD TG 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.
Result
The relative density is 1.602 at 20°C

Calculations:
Absolute density of a substance (δ) is calculated as:
δsubs = WS/Vsubs = WS/(Vpyc – Vhex) = WS/(Vpyc – WH2/δHex) = WS/(Vpyc – WH2 * Vpyc/WH1)
Relative density (D420) is calculated as: δsubs/0.999973

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
