The study was conducted to determine
the hydrolytic stability of
the test substance at three pH’s. The method used was designed to be
compatible with Method 111 of the OECD Guidelines for Testing of
Chemicals, 13 April 2004.
The test system consisted of buffer
solutions at pH’s 4, 7 and 9. A preliminary test
was performed where test substance solutions at pH 4, 7 and 9 were
maintained at 50.0 ± 0.5 °C for a period of at least 240 hours.
Results from the Preliminary Test showed it
was necessary to undertake further testing (Tier 2) at pH 9. for this further
test solutions were maintained at 50.0 ± 0.5 °C, 60.0 ± 0.5 °C and 70.0
± 0.5 °C for a period of at least 72 hours.
The results were as follows:
The estimated half-life of the test
substance at a pH of 4 or 7 is > 1 year at 25 °C. At pH 9 the test
substance estimated rate constant and half-life at 25 °C is > 1 year.
Hydrolytic stability of the test substance.
