Conclusions:
The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test was conducted in replicates and it has been observed that the substance get decomposed instead of melting. Hence, the mean decomposition temperature was determined to be 261.8°C at 97890 Pa.
Executive summary:

The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test was conducted in replicates and it has been observed that the substance get decomposed instead of melting. Hence, the mean decomposition temperature was determined to be 261.8°C at 97890 Pa.

Description of key information

Based on the available data from study report,the melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test was conducted in replicates and it has been observed that the substance get decomposed instead of melting. Hence, the mean decomposition temperature was determined to be 261.8°C at 97890 Pa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
261.8 °C
