Description of key information

2-chloropropionic acid was found to be completely miscible with water.

Key value for chemical safety assessment

Water solubility:
100 000 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of 2-chloropropionic acid is reported from three sources. Two sources report the substance to be completely miscible with water. In the other study it was stated to be soluble, but the level of solubility was not quoted. It is thought to correspond to completely miscible as the terms are often used interchangably.

It can be concluded that 2-chloropropionic acid is miscible with water. For the purposes of risk assessment a nominal value of 100,000 mg/L is assigned.
