Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 pKa of pyrrolidine was found to be 11.31 at 25 ºC.
Key value for chemical safety assessment
- pKa at 20°C:
- 11.31
Additional information
Data are available from a database and from QSAR: In Cabani et al. (1971) a value of 11.31 at 25 ºC is given (referenced in HSDB). The pKa of pyrroldine was calculated to be 10.97 at 25°C (QSAR: SPARC). This calculated value is in line with the values in the database and the experimental value. The value from Cabani et al. (1971) is regarded as the key value because the measured value is preferred above the calculated value.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
