Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The density of 2-chloropropionic acid is 1.2715 g/cm3

Key value for chemical safety assessment

Relative density at 20C:

Additional information

Eight sources of information on the density of 2-Chloropropionic acid are available. Two sources do not specify the temperature at which the density was measured and two other sources specify the temperature as 25 degrees C.

The sources cited are summarised in the table below :-

The following independent values are reported at 20 degrees C: 1.2585, 1.260-1.268, 1.268-1.275 and 1.27. These results are all in good agreement with each other. Since a single value must be reported the mean of this range is taken to be the density of 2-Chloropropionic acid - 1.27 g/cm3 at 20°C.
