Description of key information

A base-catalysed second-order hydrolysis rate constant of 0.03486 L/(mol-sec) at 25 deg C 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:
6.3 yr
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 can be regarded as 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/(mol-sec) at 25 deg C 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.
