Catechol presents a melting point equal to 105°C.
Executive summary:

Several peer-reviewed handbooks report a melting point equal to 105°C for catechol.

Description of key information

Melting point: 105°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
105 °C

Additional information

A similar value is reported in several peer-reviewed handbooks. These handbooks were grouped in only one endpoint study record which was flagged as a key study.
