Results in detail
The test item had a significantly broadened melting peak with a maximum at -11 °C, ranging from -48 °C to -9 °C in the 1 st heating (determination A and B).

The estimated accuracy is ± 1 °C.
Observed thermic processes
The melting peak showed a flat base on the low temperature side, starting at -48 °C, which comes from impurities.
Applicant's summary and conclusion
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.
