Conclusions:
The melting point determination of test chemical was done as per the test guideline OECD Guideline 102 (Melting point / Melting Range). The method followed was according to Capillary/metal block. The test was conducted in replicates and it was observed that the substance decomposes before melting. Hence, mean decomposition temperature was determined to be 161.3°C at 96430 Pa.
Executive summary:

The melting point determination of test chemical was done as per the test guideline OECD Guideline 102 (Melting point / Melting Range). The method followed was according to Capillary/metal block. The test was conducted in replicates and it was observed that the substance decomposes before melting. Hence, mean decomposition temperature was determined to be 161.3°C at 96430 Pa.

Description of key information
