Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The determination was done according to EC Guideline L 251/Al (melting-point / melting-range) with the aid of DIN 51421.
It was impossible to follow exactly the proposed procedures because of the solidification of the test substance during the cool down period, which prevented the necessary stirring. Observation of the freezing process had to be done visually, because no temperature increase or temperature plateau could be measured.
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.
