Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Item FP5440 - Key result
- Type:
- density
- Density:
- 1.271 g/cm³
- Temp.:
- 20 °C
- Remarks on result:
- other: temperature not reported, study conducted at room temperture assumed to be 20°C
- Conclusions:
- The average density of the solid test material was determined to be 1.2713 g/cm³ using a helium pycnometer.
Reference
The volume of TAOBN was evaluated to be 0.4181 cm³. Since the sample weight used was 0.5315 grams, the density was evaluated to be 1.2713 g/cm³. The helium pycnometry measurement reflects the density of the solid portion of the material excluding the pores and therefore has units of grams of solid per volume of solid assuming no closed porosity. As such, it is equal to the skeletal density of the material.
Description of key information
The skeletal density of the solid test material was determined to be 1.2713 g/cm³ using a helium pycnometer.
Key value for chemical safety assessment
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.
