The substance starts decomposing at 250° C with colour change from dark red to black and decomposition completes at 315°C.

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 substance starts decomposing at 250°C with colour change from dark red to black and decomposition completes at 315°C at 978.5 hPa.
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 substance starts decomposing at 250°C with colour change from dark red to black and decomposition completes at 315°C at 978.5 hPa.

Description of key information

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 substance starts decomposing at 250°C with colour change from dark red to black and decomposition completes at 315°C at 978.5 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
315 °C

Additional information

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 substance starts decomposing at 250°C with colour change from dark red to black and decomposition completes at 315°C at 978.5 hPa.

Based on the data obtained from the various reliable sources, the melting point of test chemical was determined to be >250°C.

Thus based on the above studies, the melting point ranges from > 250 °C to 315 °C.
