Description of key information

The test substance is considered to be hydrolytically stable.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 816 h
at the temperature of:
25 °C

Additional information

In a GLP-compliant hydrolysis study according to OECD guideline 111, hydrolysis of the testsubstance was tested at varying temperatures and as a function of pH (Ciba-Geigy Ltd., 1987).

The test substance is stable at pH 7 at 50 °C: it has a half-life time longer than one year at pH 7 at 25 °C.

Half-life time of the test substance at pH 4 at 25 °C = 157 hours.

Half-life time of the test substance at pH 9 at 25 °C = 1816 hours

The test substance is considered to be hydrolitically stable.
