Description of key information

The melting point of  1-2-hydroxyethylpyrrolidin-2-one is 26°C at 1013 hPa. 

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
26 °C

Additional information

A GLP study was conducted in accordance with the OECD Guideline for the Testing of Chemicals. 102 "Melting Point / Melting Range" using the Differential Scanning Calorimetry.T he melting point of 26°C is the peak temperature of the measurement, but the substance starts melting before 20°C. That is why a liquid has a melting point above 20°C.
