Solubility in organic solvents / fat solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- solubility in organic solvents / fat solubility
- 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 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
- Medium:
- other: ethyl alcohol
- Solubility:
- 740 g/L
- Temp.:
- 60 °C
- Medium:
- other: ethyl ether
- Solubility:
- 653 g/L
- Temp.:
- 60 °C
- Medium:
- acetone
- Solubility:
- 752 g/L
- Temp.:
- 60 °C
- Medium:
- benzene
- Solubility:
- 73 g/L
- Temp.:
- 60 °C
- Medium:
- other: chloroform
- Solubility:
- 7 g/L
- Temp.:
- 60 °C
- Medium:
- other: carbon tetrachloride
- Solubility:
- 8 g/L
- Temp.:
- 60 °C
- Conclusions:
- Catechol is soluble to very soluble in the organic solvents cited in this handbook.
- Executive summary:
This peer-reviewed handbook reported solubility values at 60°C in different organic solvents (ethyl alcohol, ethyl ether, acetone, benzene, chloroform, carbon tetrachloride). Depending on the solvents, the values ranged from 7 to 752 g/L; indicating that catechol is soluble to very soluble in these organic solvents.
- Endpoint:
- solubility in organic solvents / fat solubility
- Type of information:
- experimental study
- Adequacy of study:

Description of key information
Solubility at 20°C: 660 g/L in acetone; 582 g/L in ethanol; 19 g/L in chloroform; 1 g/L in carbon tetrachloride; 8 g/L in benzene.
Solubility at 25°C: 740 g/L in ethyl alcohol; 653 g/L in ethyl ether; 752 g/L in acetone; 73 g/L in benzene; 7 g/L in chloroform.
Catechol is soluble to very soluble in these organic solvents.
Key value for chemical safety assessment
Additional information
A reference peer-reviewed handbook and publications give consistent values of solubility in organic solvents. Therefore, a Weight of Evidence approach was applied.
