Endpoint:
flash point, other
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Data comes from peer-reviewed handbooks cited among "reference books containing peer-reviewed physico-chemical data" in the ECHA guidance document on information requirements and chemical safety assessment (R.7a).
Reason / purpose for cross-reference:
reference to same study
Qualifier:
no guideline available
Principles of method if other than guideline:
no data
GLP compliance:
not specified
Type of method:
closed cup
Flash point:
127 °C
Remarks on result:
other: Atmospheric pressure not specified

Knowing the melting point of catechol (105 °C based on reference peer-reviewed handbooks), the value above mentioned may have been obtained on the molten solid.

Interpretation of results:
GHS criteria not met
Conclusions:
Catechol presents a flash point value of 127°C. Knowing the melting point of catechol (105 °C based on reference peer-reviewed handbooks), the value above mentioned may have been obtained on the molten solid.
Executive summary:

Several peer-reviewed handbooks report a flash point value of 127°C for catechol. Knowing the melting point of catechol (105 °C based on reference peer-reviewed handbooks), the value above mentioned may have been obtained on the molten solid.

Endpoint:
flash point
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: The flash point value is just cited in the publication, without further information. Due to the consistency with the value issued from the reference handbooks, this data can be used in a weight of evidence approach.
Qualifier:
no guideline available
Principles of method if other than guideline:
no data
GLP compliance:
not specified
Type of method:
closed cup
Flash point:
127.2 °C
Remarks on result:
other: Atmospheric pressure not specified

Knowing the melting point of catechol (105 °C based on reference handbooks), the value above mentioned may have been obtained on the molten solid.

Interpretation of results:
GHS criteria not met
Conclusions:
Catechol presents a melting point value of 127.2°C. Knowing the melting point of catechol (105 °C based on reference peer-reviewed handbooks), the value above mentioned may have been obtained on the molten solid.
Executive summary:

This publications reports a flash point value of 127.2°C for catechol. Knowing the melting point of catechol (105 °C based on reference peer-reviewed handbooks), the value above mentioned may have been obtained on the molten solid.

Description of key information

Flash point range: 127 and 127.2°C (closed cup)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
127 °C

Additional information

Reference peer-reviewed handbooks and a publication give consistent flash point values. Knowing the melting point of catechol (105 °C based on reference handbooks), the values reported may have been obtained on the molten solid. Due to the consistency of the different data, a "weight of evidence" approach was thus applied.
