On the basis of the experimental
studies of the structurally and functionally similar read across
chemical and applying the weight of evidence approach, the hydrolysis
half-life value of the test chemical can be expected to be > 1 yr, at pH
range 4, 7 & 9 and at a temperature of 25°C or 50°C, respectively. Thus,
based on this half-life value, it can be concluded that the test
chemical is not hydrolysable in water.
Data available for the structurally
and functionally similar read across chemicals has been reviewed to
determine the half-life of the test chemical.The studies are as
The half-life of the test chemical was
determined at different pH range. The study was performed according to
OECD Guideline 111 (Hydrolysis as a Function of pH) at a temperature of
25°C and pH of 4, 7 and 9, respectively. The half-life value of test
chemical was determined to be > 1 yr at pH 4, 7 and 9, respectively at a
temperature of 25⁰C. Thus, based on this, test chemical is considered to
be not hydrolysable.
In an another study, the half-life of
the test chemical was determined at different pH range.The preliminary
study was performed according to OECD Guideline 111 (Hydrolysis as a
Function of pH) at a temperature of 50°C. Initial test chemical conc.
used for the study was 20 mg/l. Analytical method involve the use of
HPLC. Although the half-life value of test chemical was not known, but
at the preliminary test,the residues of the test chemical were more than
90 % in all the pH. Thus, the test chemical was reported to be stable in
water at a temperature of 50⁰C and at pH 4, 7 and 9, respectively. Based
on the half-life values, it is concluded that the test chemical is not
