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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Phys.-chem. Property |
Value |
Appearance/physical state/colour |
Red solid |
Melting point/freezing point |
No melting point up to decomposition temperature >= 270°C |
Density |
1.48 g/ml |
Particle Size Distribution |
Median: 4.51 µm |
Vapour pressure |
8.51 * 10-11mmHg (calculated) |
Partition coefficient |
log pow = 2.5 |
Water solubility |
9.80 µg/l |
Solubility in organic solvents |
3.31 mg/l (n-octanol) |
Auto flammability |
>= 270°C |
Flammability |
Combustion class no 2 (catches fire briefly and estinguishes) |
Explosiveness |
Test not required due to low exothermic decomposition energy and onset of exothermic decomposition |
Oxidising properties |
No indication of oxidising properties due to chemical structure |
Stability in organic solvents |
Stable in DMSO and sesame oil for 72 h at room temperature |
Dissociation constant |
No potential for dissociation due to chemical structure |
Minimum ignition energy (MIE) |
30 mJ < MIE < 100 mJ (with and without inductive resistance) |
Boiling point, surface tension, flash point, viscosity |
Tests not required since substance - decomposes before melting - is a solid - has water solubility < 1 mg/l

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.
