Description of key information

A base-catalysed second-order hydrolysis rate constant of 0.03486 L/mole-sec was estimated using a structure estimation method. This corresponds to half-lives of 6.3 years at pH 7 and 230.2 days at pH 8.

Key value for chemical safety assessment

Half-life for hydrolysis:
230 d
at the temperature of:
25 °C

Additional information

In accordance with REACH Regulation 1907/2006, Annex VIII, Column 2 hydrolysis as a function of pH does not need to be determined as the substance is readily biodegradable.

Stability of the substance against hydrolysis was calculated using the computer program HYDROWIN (v 2.00). A base-catalysed second-order hydrolysis rate constant of 0.03486 L/mole-sec was estimated using a structure estimation method. This corresponds to half-lives of 6.3 years at pH 7 and 230.2 days at pH 8.
