Any other information on results incl. tables

This material has no groups that are susceptible to hydrolysis in the pH 4 to 9 range; therefore, it is considered stable to hydrolysis in surface and groundwater. It is estimated to have a hydrolysis half-life of greater than one year between pH 4 and pH 9.
The estimation program in EPIWIN 4.1 has no capability to estimate hydrolysis rates for this compound.
