Additional information

Flask method (OECD 105). The concentration of test item in the sample solutions was determined by high performance liquid chromatography (HPLC).


It should also be noted that due to the rapid hydrolysis of the test item the saturation concentration can only be maintained in the presence of a large excess of test item. Therefore this value should be considered as a worst case in that any solution will quickly hydrolyse, removing the test item from solution.
