Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 the test item is 10.8 at ca. 24 °C.

Key value for chemical safety assessment

Additional information

The dissociation constant of the test item was determined according to OECD Guideline 112 by the titration method.

The mean value of three determinations at room temperature (approx. 24 °C) was pKa=10.8.

The test item has several amino groups with obviously very similar pka values, so that only one mean pKa value for the test item could be determined.
