Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Key study:- Tarran (2012) OECD 102, EU Method A.1, The test substance melted with decomposition from approximately 282 °C (555 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 282 °C
Additional information
In the key study, the determination of the test material melting point was carried out by differential scanning calorimetry (DSC) using a procedure designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
A reliability score of 1 was assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
The test item has been determined to melt with decomposition from approximately 282 °C (555 K).
Several sources were available as supporting information:
Chemical Book (2012) and Look Chem (2012), both list the product specification of the registered substance. No information relating to the method of generating the data, original source or GLP status were provided accordingly, a reliability score of 4 was assigned, in line with the principles for data quality as described by Klimisch (1997). The substance was reported to decompose between 245 and 248 °C.
Information was also available in the following MSDS
WITCO (2000): Decomposes at ca. 230 °C
GELEST (2003): Decomposes between 245 and 248 °C
No information regarding the performance of the observations was included in the summary. The information in these sources was presented only as a short abstract as part of a MSDS. A reliability score of 4 was therefore assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
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.
