Description of key information

The test substance is the hydrochloride of a zwitterion and by this the test substance dissociates in water to chloride and the zwitterion. The acidic and basic groups of the zwitterion dissociate, depending on the pH.
The dissociation constants of the zwitterion of the test substance were estimated by an atom/fragment contribution method. The pKa values for the zwitterion of the test substance are 0.8 (acidic), 6.9 and 8.6 (basic).

Key value for chemical safety assessment
