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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- internal method G03302 SPECIFIC GRAVITY AND DENSITY AT 25°C (BY PYKNOMETER)
- Principles of method if other than guideline:
- Because of the substance's water insolubility it was possible to measure the density by water displacement within a pyknometer (see under results).
- GLP compliance:
- no
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 1.018 other: no unit
- Temp.:
- 25 °C
- Type:
- density
- Density:
- 1.018 other: g/mL
- Temp.:
- 25 °C
- Conclusions:
- Density at 25°C 1.018 g/mL
Reference
Wt. Pyknometer : 45.331g
Wt. Pyknometer + water : 144.929g
Wt. Pyknometer + sample only : 75.629g
Wt. Pyknometer + sample+ water: 144.538g
Wt sample added = 75.629 – 45.331 = 30.298g
Wt of water to fill pyknometer = 144.929 – 45.331 = 99.598g ->99.888ml @25degC
Wt of water added = 145. 538 – 75.629 = 69.909g -> 70.112ml @25degC
Therefore Volume of sample = 99.888 – 70.112 = 29.776ml
Therefore density of sample = 30.298/29.776 = 1.018g/ml
Description of key information
Density at 25°C 1.018 g/mL
Key value for chemical safety assessment
- Relative density at 20C:
- 1.018
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.
