Description of key information
Additional information
The substance is a black organic powder at 101325 hPa and 20 °C.
Between 40 and 160 °C, there is release of imbibition water/solvent, followed by a degradation between 276 and 421 °C (onset at 314.2 °C, enthalpy = 222.9 J/g ).
The relative density was determined by means of a pycnometer and recorded at 1.535 at 20 °C.
The particle size distribution of the test item was analyzed using the Mastersizer 2000 tool and the D50 resulted was 28.875 µm.
The substance is very soluble and LogKow value was calculated as -2.2155.
Properties like vapour pressure, surface tension and flash point can be neglected.
The substance is not flammable and it is not expected to be auto-flammable, explosive and it is deemed to be potentially not oxidising based on the chemical structure and the known experience in the handling and use of the substance.
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.
