Additional information

The assessment of hydrolytic stability of the test compound was carried out according to OECD 111 (2004). At pH 9 the substance was found to be stable (t1/2 = 407 days), whereas at pH 4 and 7 degradation/losses of test item did not follow typical temperature dependency. Thus the Arrhenius relationship could not be applied to extrapolate the half-lives at 25 °C and additional testing was performed at pH 4 and pH 7 at 25 °C over an extended period of 28 days (pH 7, 25 °C, t1/2 = 41.9 days; pH9, 25 °C, t1/2 = 82.4 days).

Further tests on abiotic degradation of the substance are not available and not required.
