Catechol presents a boiling point equal to 245.5°C at ambient pressure.
Executive summary:

Several peer-reviewed handbooks reported a boiling point equal to 245.5°c at ambient pressure for catechol.

Description of key information

245°C at 1000 hPa to 245.5°C at 1013 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
245.5 °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.
