Description of key information

Hydrolysis:

On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be ranges 7.3  yr, at pH range 7 and 270 days at pH 8 by base catalysed second order hydrolysis rate constant. Thus, based on this half-life value, it can be concluded that the test chemical not hydrolysable in water.

Additional information

Hydrolysis:

Data available for the test chemical has been reviewed from authoritative database (HSDB, 2017) to determine the half-life of hydrolysis as a function of pH. The studies are as mentioned below:

In first weight of evidence study the half-life and base catalyzed second order hydrolysis rate constant was determined using a structure estimation method of the test chemical The second order hydrolysis rate constant was determined to be 0.03L/mol-sec with a corresponding half-lives of 7.3 yrs and 270 days at pH 7 and 8, respectively. Based on the half-life values, it is concluded that the chemical is not hydrolysable.

In another study the test chemical is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions

On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be ranges 7.3  yr, at pH range 7 and 270 days at pH 8 by second order hydrolysis rate constant. Thus, based on this half-life value, it can be concluded that the test chemical not hydrolysable in water.
