Link to relevant study record(s)

Reference

Reference 1

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).

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.

Executive summary:

This publication reported solubility values at 20°C in different organic solvents (ethyl alcohol, acetone, benzene). Depending on the solvents, the values ranged from 8 to 660 g/L; indicating that catechol is soluble to very soluble in these organic solvents.

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.

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.
