Description of key information
The test item is a non-combustible, non-oxidizing crystalline solid of white color. The test item has no melting point under atmospheric conditions but undergoes decomposition at approximately 245 °C. The relative spontaneous ignition temperature is 384 °C (decomposition products included). At 20 °C, the water solubility is 186 g/L (at pH 5.8) and the corresponding partition coefficient octanol / water (log Pow) estimated by QSAR is -2.63. The solid compound has a relative density of 1.58 at 20 °C. The vapour pressure is 0.0025 Pa at 150 °C. The particle size distribution of the test item is:
> 400 µm: 54.2 % of the particles;
> 150 µm: 39.2 % of the particles;
> 0 - < 150 µm: 9.8 % of the particles.
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.
