Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Data comes from a peer-reviewed handbook 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:
- other: no data available
- Water solubility:
- 804 g/L
- Temp.:
- 60 °C
- Remarks on result:
- other: No information on pH are available.
- Conclusions:
- Very soluble (> 10000 mg/L)
Catechol presents a water solubility value equal to 804 g/L at 60°C. - Executive summary:
A peer-reviewed handbook reports a water solubility value of 804 g/L at 60°C for catechol; indicating it is very soluble into water.
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Data comes from a peer-reviewed handbook cited among "reference books containing peer-reviewed physico-chemical data" in the ECHA guidance document on information requirements and chemical safety assessment (R.7a). A publication, cited in the same endpoint study record, gives an identical value as the handbook.
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- No data
- GLP compliance:
- not specified
- Type of method:
- other: no data available
- Water solubility:
- 451 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: No information on pH are available.
- Conclusions:
- Very soluble (> 10000 mg/L)
Catechol present a water solubility value equal to 451 g/L at 20°C. - Executive summary:
A peer-reviewed handbook and a IUPAC publication report a similar water solubility value of 451 g/L at 20°C for catechol; indicating it is very soluble into water.

Description of key information
Water solubility range: 235 to 584 g/L at 20 - 25°C.
Catechol is thus very soluble in water.
Key value for chemical safety assessment
- Water solubility:
- 517.5 g/L
- at the temperature of:
- 20 °C
Additional information
Reference peer-reviewed handbooks and publications give consistent values, reflecting a high water solubility of catechol. Two key studies (klimish 2) and two supporting studies (klimish 4) are available. An average of all the data at 20 °C was calculated to obtain the key value for chemical safety assessment.
