Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- at the temperature of:
- 20 °C
Additional information
Five endpoints on the vapour pressure of 2-Chloropropionic acid are available tabulated below and standardised to kPa
| Source | Value | Units | Temperature | Value Standardised to kPa | IUCLID Reference |
| Sigma Aldrich Library of Chemical Safety Data (2nd Edition) | 4 | mm/Hg | 20 | 0.5 | 001 |
| Inchem.org | 0.1 | kPa | 20 | 0.1 | 002 |
| IUCLID Dataset - BASF AG | 4 | hPa | 60 | 0.4 | 003 |
| IUCLID Dataset - BASF AG | 30 | hPa | 100 | 3 | 003 |
| Sigma Aldrich Safety Data Sheet | 5 | hPa | 20 | 0.5 | 004 |
Since vapour pressure increases with temperature it is important to only consider results from the same temperature, so 20 degrees C is the chosen temperature, since the majority of results are available from this temperature. Standardising the results to units of kPa the available data indicates a vapour pressure of 0.5, 0.5 and 0.1.
Due to consistency between two independent values and the fact that one of the sources was peer reviewed, it is considered that 0.5 kPa at 20 degrees C can be taken to be the vapour pressure of 2-chloropropionic acid.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
