Conclusions:
The Mean melting temperature range of test chemical was determined be 169.6 - 172.8°C at 969.4hPa.
Executive summary:

The melting point determination of test chemical was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean melting temperature range was determined to be 169.6 - 172.8°C at 969.4hPa.

Description of key information

The Mean melting temperature range of test chemical was determined be 169.6-172.8°C at 969.4hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
169.6 °C

Additional information

The melting point determination of test chemical was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean melting temperature range was determined to be 169.6 - 172.8°C at 969.4hPa.

Other supporting study from various reliable sources such as authoritative database and handbooks also indicated that the melting point of test chemical was observed in the range of 170 degree C to 177 degree C, which was very close to selected key study value.
