Description of key information

NPPT has a melting point of 91 °C at 1013.25 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
91 °C

Additional information

Two GLP study were conducted. Both results the melting point to be in the same range. The test item NPPT has a melting point of 91.4 °C at atmospheric pressure (1013.25 hPa) as determined according to Directive EC 440/2008 Method A.1 (GLP study) and of 91 °C at atmosphere pressure (1013.25 hPa) as determined according to the OECD­Guideline for the Testing of Chemicals 102 (GLP study). The value from the OECD-guideline-study was chosen as key value.
