168.6 °C
Atm. press.:
1 013 hPa
Decomposition:
no
Remarks on result:
other: atmospheric pressure assumed

A melting point value of 168.6°C at 1013 hPa was determined in a reliable study conducted according to an appropriate national guideline.

Description of key information

Melting point: 168.6°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
169 °C

Additional information

Melting point values of 168.6 and 170.1°C were determined in a reliable company report. Both studies were conducted according to appropriate standard test method and national guideline, respectively. As a conservative approach the lower melting point was selected as the key study.
