Description of key information

The substance was found to hydrolyse under environmental conditions. The hydrolysis reaction followed pseudo-first order reaction kinetics. It was observed that more rapid hydrolysis occurred under more alkaline reaction conditions.

Key value for chemical safety assessment

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

Additional information

A valid hydrolysis study in accordance with OECD TG 111 was conducted. The results of a preliminary test indicated that further testing is required and the hydrolysis was studied in a main test at pH 4, pH 7 and pH 9 with sample solutions being maintained at 30 °C, 40 °C or 50 °C. It was found that the substance was hydrolysed under all test conditions and that the reaction followed pseudo-first order kinetics. The rate constants for the reaction at 25 °C were estimated by using the Arrhenius relationship and were 0.00229 hr-1 at pH 4, 0.000997 hr-1 at pH 7 and 0.0054 hr-1 at pH 9. This corresponds to half-lives of 302 hours, 695 hours and 128 hours, respectively.
