Description of key information

The hydrolysis of a structurally very similar substance was tested according to OECD TG 111 (2004) and EU Method C.7 (2008). The test substance was found to be not hydrolytically stable. Half-lives at pH 4 and pH 9 were significantly below 10 minutes at 20 °C. The half-life at pH 7 was 449 (433-466) minutes at 20 °C, 225 (220-230) minutes at 30 °C and 87.0 (81.6-92.4) minutes at 40 °C. The correlation coefficients r2 were 0.996, 0.997 and 0.994 at these temperatures, confirming pseudo-first order kinetics.
