Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The mean melting temperature range of test chemical was determined to be in the range of 62-65.6°C at 966.5 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 mean melting temperature range was determined to be 62-65.6°C at 966.5 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 mean melting temperature range was determined to be 62-65.6°C at 966.5 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
62 °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 mean melting temperature range was determined to be 62-65.6°C at 966.5 hPa.

Other supporting data from review article, handbook and reliable databases also indicates the melting point of the test chemical was determined to be in the range of 66 to 71 Deg C, closer to the selected key value.
