Description of key information

Melting point = 25 °C

This low melting point is the reason, why 2 -pyrrolidone is also sometimes referred to as a "low-melting solid".

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
25 °C

Additional information

A melting point of 25 °C was determined by Flick E.W. (2010) and reported in the peer-reviewed database GESTIS (2010).
