Description of key information

One valid key study is available to assess the abiotic degradation of the registered substance. This study was performed according to a method equivalent to OECD Guideline 111 (Hydrolysis as a Function of pH) with GLP statement. The substance failed to hydrolyse at pH 4 and pH 7 (at 50°C) while more than 10% hydrolysis was observed after 5 days in pH 9 (at 50°C). Therefore the main test was performed at pH 9 and directly at 25°C. The rate constant at pH 9 and 25°C was measured at 8.60 x 10-7s-1, which corresponds to a half-life of 224 hours.
