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 observed to be 208.5-213.5°C at 967.3 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
208.5 °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 found to be 208.5-213.5°C at 967.3 hPa.

Based on other supporting data from authoritative databases, the Melting point of test chemical is determined to be 213 °C.

Other supporting data from authoritative database Gestis, also supported the selected key study and exhibited the Melting point of test chemical as 200 °C, closer to the selected key value.
