Description of key information

One key study was provided, performed to current guidelines and GLP. A values of 4.87 g/L at 19.7oC, pH 4.7 is taken as the critical value.

Key value for chemical safety assessment

Water solubility:
4.87 g/L
at the temperature of:
19.7 °C

Additional information

A recent study has been performed to current guidelines and to GLP. This study (Mahmood, T. 2011), used as the key study, determined the water solubility of 2, 4-Dichlorophenol to be 4.87 g/L at 19.7°C.

In addition to the key study, a total of eight supporting water solubility values are reported from the literature. These are summarised in the table below:-

Where the temperature is indicated, the water solubility is in close agreement; the most consistent value reported being 4.5 g/L at 20 °C. This value is comparable with the value obtained in the key study, however the purity of the material tested in the literature values is not reported.

As the quality of the data in the key study has been evaluated as Klimisch 1, the result from the key study is adopted as the endpoint value. Substances with a water solubility of 1000-10000 mg/l are regarded as soluble. Since 2, 4 -Dichlorophenol has a solubility of 4,870mg/l (4.87 g/l) in water it is therefore regarded as soluble.
