Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- density, other
- Remarks:
- absolute density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 27 Jul 1999
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:
- no
- Type of method:
- other: graduated cylinder
- Key result
- Type:
- other: absolute density
- Density:
- 1.65 g/cm³
- Temp.:
- 40 °C
- Conclusions:
- A density of 1.65 g/cm3 at 40 °C was observed for MeFBSA (liquid form).
- Executive summary:
The density of MeFBSA was determined by pouring melted substance into a graduated cylinder and measuring weight and volume at that temperature. The study was performed comparable to OECD guideline 109 but with limited detail on the study. The graduated cylinder, while certified, is of relatively limited accuracy for volume measurements as compared to a pycnometer. Therefore the study is considered reliable with restrictions.

Additional information
In the key study, the density of MeFBSA was determined by pouring melted substance into a graduated cylinder and measuring weight and volume at that temperature. The study was performed comparable to OECD guideline 109 but with limited detail on the study. The graduated cylinder, while certified, is of relatively limited accuracy for volume measurements as compared to a pycnometer. Therefore the study is considered reliable with restrictions. In the supporting study, the molten substance was similarly poured into a graduated cylinder but allowed to solidify overnight. Phase changes are often accompanied by a change in volume, but no information was provided on how the top of the material was kept level and flat during cooling and solidification in the graduated cylinder. The melt density is considered more accurate and is the preferred value.
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).
