Description of key information
Determination of the Dissociation constant of the isomer p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline (496981)
(GLP compliant study based on the OECD Guideline 112, 1981)
Author: Dr. Ir. E. Baltussen
Key value for chemical safety assessment
- pKa at 20°C:
- 3.25
Additional information
The Dissociation constant of the isomer p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline was determined based on the procedures indicated by the internationally accepted method from the OECD Guideline 112.
The pKa value was determined for p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline using the spectrophotometric method. This pKa value determined for p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline is 3.25 and corresponds to the dissociation of a basic group in the molecule. It is considered that the pKa value of
m-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline is similar
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
