Description of key information

The hydrolysis behaviour of Canrenone was examined at different pH values. At pH 4 the test substance is hydrolytically stable, at pH 7 it is hydrolyzed very slowly and at pH 9 the substancance is hydrolyzed with a half-life of 6.4 days. The hydrolysis is therefore base-catalyzed. For pH 9, the rate constant (25 °C) of 0.004484 h-1 and a half-life t1/2 of 6.4 d were determined.

Key value for chemical safety assessment

Half-life for hydrolysis:
6.4 d
at the temperature of:

Additional information

The half-life for hydrolysis was determined at pH 9.
