Description of key information
The substance is a red powder at 1013 hPa and 20 °C.
Melting occurs between 124 and 149 °C; exothermic decomposition occurs between 278 and 357 °C with an energy release of 507.3 J/g.
The relative density was not determinable due to the solubility of the substance in various organic solvents. Granulometry analysis gave a MMD of 4.423 µm.
The substance has low solubility, i.e. below 20 mg/l, in water at 20 °C at pH 4.32. Average log Pow is 1.4420. Vapour pressure was estimated to be low, i.e. 7.06E-8 Pa at 25 °C.
Surface tension and flash point can be neglected.
Experimental data and/or known experience in handling and use indicate the substance as non flammable, non explosive and devoid of oxidising 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.
