Additional information
A melting point value of -57.7°C is reported in two collections of reliable data. These results are considered to be reliable and the most recent is assigned as key study. The results given in several other secondary sources, to which a reliability could not be assigned, are in the range of -55 to -58°C and therefore support the key study result. Differences in the melting point may be due to impurites in the sample during testing.
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.
