Reference
According to the DSC-measurement in a closed glass crucible it can be stated that the test item boiled under decomposes at a temperature of approximately 260 °C.
Validity criteria for the measurement of the melting point:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The mean of at least two measurements which are in the range of the estimated accuracy should be reported. | The value is the mean of two runs. The values differed in 2.6 °C and do not lie within the accuracy specified in OECD TG 102 for differential thermal analysis (+/- 0.5 K). | No. However, in order to specify the results of the DSC measurement an additional measurement with the capillary method was performed and the onset temperature of 260 °C. |
| The pressure(s) at which the measurements were made shall be reported. The pressure should preferably be close to normal atmospheric pressure. | Pressures were stated and were close to normal atmospheric pressure (1027 and 1022 hPa). | YES |
Description of key information
The test item boils under decomposes under atmospheric conditions at a temperature of approxi-mately 260 °C.
Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 260 °C
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.
