Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- relative density
- Density:
- 1.49 other: relative density
- Temp.:
- 21.7 °C
- Conclusions:
- Under the conditions of the test, the density of the test substance was calculated as 1.4877 g/cm3 at 21.7°C. The relative density (compared to water at 4°C) was 1.49.
- Executive summary:
A study was conducted to determine the relative density of the test substance according to OECD Guideline 109 and EU Method A.3, in compliance with GLP.
The relative density of the test substance at room temperature was measured by the air comparison pycnometer method (Micrometries MultiVolume Pycnometer 1305, Sar. No. 932). The volume of the test substance was measured with Helium in a cylinder of variable calibrated volume. Two test series with different weights were carried out in air. For the calculation of density, a mass measurement was taken after concluding the volume measurement.
Under the conditions of the test, the mean density of the test substance was calculated as 1.4877 g/cm3 at 21.7°C. The relative density (compared to water at 4°C) was 1.49.

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.
