Conclusions:
The melting point of test chemical was determine be greater than 360°C at 975.6hPa.
Executive summary:

The melting point determination of test item was done following OECD Guideline 102 and according to the metal block capillary method. no change was observed in state of test item upto 360 deg c, inferring melting point to be greater than 360 deg C at 975.6 hPa.

Description of key information

The melting point of test chemical was determine be greater than 360°C at 975.6hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
360 °C

Additional information

The melting point determination of test item was done following OECD Guideline 102 and according to the metal block capillary method. no change was observed in state of test item upto 360 deg c, inferring melting point to be greater than 360 deg C at 975.6 hPa.

Other supporting data from authoritative database and another report, also supported the selected key study and exhibited the melting point of test substance is greater than 300°C and greater than 400°C.
