key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

data from handbook or collection of data

Remarks:

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

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.

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.
