Numerous badly defined transformations occurred between + 19 and + 28.6 °C. A clear statement about the solidification is not possible.
Description of key information
The melting/freezing point of the test substance was determined in a study and reported in a number of data sheets and the value was 28 °C and 29 °C. These values are in accordance with data from authoritative online databases (GESTIS & Beilstein) where the melting/freezing point was measured within the range of 28 - 30 °C. In the oldest available study numerous badly defined transformations occurred between + 19 and + 28.6 °C. However, a clear statement about the solidification is not possible.
Key value for chemical safety assessment
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.
