Description of key information
The test substance is a beige coloured solid.
A melting point of 82°C at 1025 mBar was measured by differential scanning calometry (EU method A.1).
The substance shows a boiling temperature and/or thermal decomposition earliest at ca. 265°C at 1025 mBar as determined by differential scanning calometry (EU method A.2).
Relative density was determined as 1.412 at 20°C by the pycnometer method according to OECD guideline 109.
In granulometry measurements according to DIN 66165 a mass median aerodynamic diameter of particles of 1724 µm was measured by sieving.10th- and 90th percentiles were determined as 1432 µm and 2025 µm respectively in this study.
A vapour pressure of <=0.061 Pa at 20°C and <= 2.2 Pa at 50°C was measured by the dynamic method according to EU method A.4.
The octanol/water partition coefficient (log Pow) is 1.644 at 23 °C and pH 7.27,measured with the HPLC method in accordance with EU method A.8.
A water solubility of 5.2 g/L at 20°C and a pH-value of 6.55 was determined according to OECD guideline 105 by using the flask method.
The surface tension at 21°C of a 1.0 g/L aqueous solution is <= 63.1 mN/m, measured by using the ring method according to EU method A.5.
A flash point of 148°C at 1013.0 mbar was determined by the closed cup method using a Setaflash apparatus (EU-method A.9).
In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.12 a self-ignition study according to EU method A.16 does not need to be conducted for solids with melting points < 160 °C and was therefore not performed.
The test substance is not highly flammable based on a preliminary screening test according to EU Method A.10.It was also tested according to EU methods A.12 and A.13 and was found to be neither flammable in contact with water nor to have pryrophoric properties.
In a study to determine explosive properties according to EU method A.14, the test substance did not have explosive properties as determined by thermal and and mechanical (shock and friction) sensitivity tests.
In a study according to EU method A.17 the test substance did not have 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.
