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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Appearance/physical state/colour:
The substance is a crystalline white powder with a characteristic odour.
(Source: GLP-report)
Melting point:
A melting point could not be determined, as the substance starts to sublime at 191°C.
(Source: GLP-report)
Boiling point:
The study does not need to be conducted, because the substance is a solid which sublimes before boiling. Sublimation point was found to be 191°C.
(Source: GLP-report & exert assessment)
Density:
The density was found to be 1.27 g/cm3 at a temperature of 20°C.
(Source: GLP-report)
Particle size distribution:
3.29% of the particles analyzed were found to be < 10 µm and 5.35% < 20 µm. D10 was 41.21 µm, D50 was 139.29 µm and D90 was 334.47 µm.

Vapor pressure:
The vapor pressure was determined to be 6.6 Pa at 25°C.
(Source: GLP-report)
Partition coefficient n-octanol/water:
The log Pow was determined to be 0.12 at a temperature of 20°C.
(Source. GLP-report)
Water solubility:
The water solubility of the test item is 0.222 g/l at a mean temperature of 21.5°C.
(Source: GLP-report)
Surface tension of an aqueous solution:
The surface tension was found to be 71.9 mN/m (0.204 g/l solution) at 19.5°C. The test material is considered not to be a surface-active material.
(Source: GLP-report)
Flash point:
The flash point was found to be 50-55°C, using a closed-cup Pensky-Martens apparatus.
(Source: non-GLP-report)
Auto flammability:
The relative self-ignition temperature of the test item is > 400°C.
(Source: GLP-report)
Flammability:
The substance is highly flammable and needs to be classified as flammable solid, Cat.2. Based on the chemical structure, the test item does neither react with water nor evolve any flammable gases in contact with (humid) air.
(Source: GLP-report and expert assessment)
Explosiveness:
The test material did not show any explosion or other reaction in the three parts of the EU test method A.14 and has therefore been determined not to have explosive properties.
(Source: Expert assessment)
Oxidizing properties:
From the assessment of the chemical structure it was established that the test substance would not have oxidizing properties.

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.
