Half-life (20 °C) at pH 4: 95 h (OECD 111)Half-life (20 °C) at pH 9: 1117 hno hydrolysis at pH 7 (preliminary test)
One study investigating the hydrolysis of the test substance is
The hydrolysis study was conducted according to OECD guideline 111 and
GLP (Meinerling and Herrmann, 2012). In a preliminary test at pH 4, 7
and 9, significant reduction of the test item concentration was observed
at pH 4 and pH 9. In the main test the half-life of the test substance
was therefore determined in solutions buffered at pH 4 and pH 9. The
solutions were incubated at 20 °C, 40 °C and 50 °C. The concentration of
the test item was determined by HPLC. The half-life of reaction at 20 °C
was determined to be 95 h at pH 4 and 1777 h at pH 9. In conclusion, the
test item is stable at pH 7, and hydrolysis at pH 4 and 9 is slow.
Hydrolysis is thus not expected to be a relevant process for this
substance in the environment.
